"Making custom mouthpieces is one of the main reasons I opened up my shop. I wanted to make a mouthpiece that felt comfortable, had a rich sound full of overtones, and didn't zap my endurance! After a lot of time on the lathe, I'm proud to say I've developed a comprehensive offering of mouthpieces sizes for any gig! We have the absolute highest tolerances in the industry!" -Trent Austin

Here's a quick video where I discuss some different options I've been playing lately:



Check the insides of some of my most popular sizes!



I also think it's important to have a mouthpiece that looks good! To do this, I've developed a number of blanks (outside shapes) to balance weight, resistance, and player feedback to make your playing more enjoyable and more efficient!



This video is a live session where I discuss the mouthpiece blank options we offer at ACB! 




Most of our ACB mouthpieces are in stock in the standard blank. Other ACB blanks are custom made to order and may not be in stock. Please review the comparison sheet for size equivalencies.


Please note that almost every manufacturer measures in slightly different places so the comparison information below is for broad comparisons only.

Larger  Sized  ACB  mouthpieces (.674+) : 

  • Papa Bear: This mouthpiece is not for the faint of heart! It has an extremely large mouthpiece (.684) which puts it around an old Bach 1 diameter.  The cup is a large bowl, throat #20 and a custom backbore give this piece the most efficiency while maintaining a HUGE sound.  
  • Bee Bear: Similar to the Papa this mouthpiece has a medium large,  b-shaped bowl, and slightly smaller backbore.
  •  New York 1: This originally started out as a CMM scan of a very early New York Bach 1 mouthpiece.  The cup and rim are very similar, the backbore and throat are matched with this cup to produce a very large sound shape. This is a great orchestral mouthpiece!
  • 1C: This is my take on an older Bach 1C but with an improved throat and backbore combo. It feels significantly more efficient and sounds more energized while maintaining a rich core throughout all registers. This mouthpiece has our standard 24 throat and 10/24 combo backbore.


Smaller Symphonic sized mouthpieces (.668-674):

  • 1.25 CB: This has a classic Bach Mt. Vernon 1-1/4C mouthpiece rim that's blended in the CAD  program with a great old Bach 5B cup. The result is an incredibly rich sounding mouthpiece without losing efficiency or having the turbulent points caused by a traditional "screw-rim"  setup.
  •  1.25C: This is  a take on a great 1 1/4C  mouthpiece with some refinements in bore, backbore, and throat. To me it feels more like a 1.5C due to the great efficiency. 
  • 1 1/2B: This is a great sounding orchestral mouthpiece. While not as wide as the Papa Bear (the diameter is like a modern 1 1/2) the rim is comfortable and forgiving. The cup bowl is reminiscent of some rotary trumpet mouthpieces. I've always loved those mouthpieces, but the backbores and end shanks are really not made for conventional piston trumpets. My mouthpieces are made to work with piston trumpets and still work really well in rotary trumpets! 
  • 1 1/2C: This is one of my best-selling mouthpieces and extremely comfortable compared to other manufacturer's  "cookie cutter" rim contoured 1 1/2's.
  • 1.5 CB: Similar to the 1.25 CB with my ACB 1 1/2C rim


Classic "MV"  diameter sized pieces (based on a great Bach Mt. Vernon rim): 

  • MV 1 1/4C: This is my modernized take on the Bach Mt. Vernon 1-1/4C mouthpiece.  I match this piece with my O backbore and a slightly enlarged throat and throat entrance. It plays incredibly well and also has a very "classic" sound!
  • 665MC: Slightly larger than the MV 3C, this has a more efficient cup shape than on my MV 3C mouthpieces.
  • MV 3C: Another special mouthpiece, please check out this link for more info:
  • MV3CS: MV3C rim with my CS cup -- it's  slightly smaller and also has a much more efficient entrance into the throat. This helps the articulation and adds a lively "zip"  to the sound. This mouthpiece is especially good on vintage trumpets or overly dark horns to make them "speak." Paired with the MO backbore for a balanced feel.


Medium sized Standard series Mouthpieces (.630-656)

  • 3: My take on a classic 1928 mouthpiece. I tweaked a bunch inside this mouthpiece and while it still retains the core sound the piece plays considerably more efficiently and consistently in all the registers.
  • 3B: Same rim as on my 3C but with a medium deep B-shaped bowl.  It's one of my most popular mouthpieces and has an incredibly warm tone!
  • 3C: My take on a fantastic Bach 3C mouthpiece from the late 60's; I have never played a 3C  like it. I think the added mass and proper matching backbore make this a formidable all-around mouthpiece!
  • 3CS: Similar to the 3C except it's slightly smaller and has a much more efficient entrance into the throat. It helps the articulation and adds a lively "zip" to the sound. This mouthpiece is especially good on vintage trumpets or overly dark horns to make them "speak".
  • 5B: My modernized take on one of the finest mouthpieces ever made, the Bach New York 5B. I've made the ACB 5B mouthpiece much more efficient than the vintage counterpart while maintaining the great sound shape and spread.  It's one of my most popular sizes.
  • 5C: Long considered a transitional mouthpiece for the student, I've spent a bunch on time on this piece as most of my earlier prototypes didn't make the cut. This mouthpiece has an incredibly rich tone with fantastic articulations and ease in all registers.  It's a great, comfortable mouthpiece!


Smaller diameter Standard Series  Mouthpieces:

  • 10 1/2C: While this is a fairly small diameter mouthpiece it produces a big tone, with a fine high register and resonating low register. I started with this piece thinking it would a good mouthpiece for students to start on, but I find it very good for all players, especially those with very thin lips and ones who want a bit more corner support.
  • 10CV: Another new addition to the line, this mouthpiece was made for folks who want a compact efficient commercial mouthpiece but who "bottom-out" on smaller pieces. This rim is very similar to an older Giardinelli 10 and the cup a medium shallow  hybrid v/bowl shape.  The result is a very good all-around show and commercial mouthpiece. It's also an excellent choice for jazz soloists looking for a piece for extended solo work.  
  • 1-27: This is my take on a fantastic vintage piece, the Al Cass 1-27. The cup and rim are loosely based off the Al Cass mouthpiece. I then used a slightly more aggressive entrance into the bowl of the mouthpiece and also a tighter backbore to make the piece zip even more. The inner diameter is around a 7C but with a round and comfortable rim. The cup volume is less than a 7C for sure, so this mouthpiece has a lot more efficiency and sparkle to the sound.
  • Lead 1.25: I've always loved the cup of the Marcinkiewicz Shew 1.25, and played on that mouthpiece for many years. I felt the piece's weight, straight throat, and backbore could be improved for my own use. I designed this mouthpiece to feel more forgiving (especially in this blank) and gained more core in the overall sound shape. This mouthpiece is a weapon for the commercial trumpet player!


TA Series (designed for my own personal playing needs)

  • TA2:
    It has a cup  design which while being fairly shallow bowl shaped has an efficient entrance into the bottom of the cup to make it very efficient without sounding brittle. The rim is semi-flat with good support and is close to a "3-ish" diameter (.664). 
    The TA1 is still my primary piece and I find it fantastic for everything but lead and show playing. That's where the TA2 comes in for me. It feels like a great show mouthpiece. I remember one gig where I played it on some 3 horn Sinatra arrangements and it was great to solo on and then sizzles above high C without getting smaller in sound shape.  
  • TA-Lead: This is  a model I've created for my own lead mouthpiece use. This rim is extremely comfortable, similar to an old Giardinelli 10S mouthpiece but rounder and more forgiving. The cup depth is shallow enough for great compression yet produces an incredibly rich tone in all registers. Standard 28 throat and my "zip" backbore round out this model. It's a great lead mouthpiece for people who tend to "bottom out" on small cups.
  • TA-Screech: A new take on a classic piece... this is a very small, high compression mouthpiece that is surprisingly easy to play. 30 throat and "zip" backbore produces one of the most efficient lead mouthpieces I've ever played! 
  • TA-Z: The TA-Z (or "Zing") might be one of the most comfortable commercial mouthpieces I've designed that can still maintain a beautiful sound from Pedal C to Double C and above. It features a .625 diameter with a medium flat rim and shallow hybrid V/S cup.  


Here is a list of our backbores in order of tightest to most open:

KA3: our newest commercial backbore and it is amazing! Feels almost like the throat is one size smaller due to the compression

KA2: a very nice backbore with good zing.

KA1: more core than the A2 and a bit tighter as well.

A2: The A2 is a weapon!  Designed to be mated with extreme compression mouthpieces,  this might be the ultimate commercial backboreI've played.  It works great above high C and mates with 27, and 28 tops extremely well!

T:  Tight:  commercial backbore which provides the most resistance and "zing"  to your sound

MT:  Medium Tight:   Provides great resistance, especially for players who tend to "back-up"  with very tight commercial backbores.

S:  Standard:   Provides the best balance between resistance and sound spread for most players. 

MO:  Medium Open: A great slightly open symphonic shape produces a rich,  warm tone but still gives ample resistance when needed.  

A1:  This backbore is a very large, symphonic backbore that is in between the MO and O  but feels like it combines both feel and sound shapes from the two other shapes.  It's  a wonderful backbore suited for the classical player or jazz soloist wishing for a large sound!

O:   Open:   This is a very large, open backbore designed for the orchestral musician to provide the feel and sound spread that most orchestral players prefer

OO: Very Open:  Huge backbore for enormous, rich sound (takes a lot of air)





The following audio samples are raw with no added effects and totally live. Getting the shop up and running has taken a bit out of my efficiency. I literally went from one piece to the next with no breaks (not ideal when you go from a huge orchestral piece to an efficient lead piece in less than a minute). The differences are more noticeable in these audio clips:

Great Mouthpiece
Written by Brandon Walsh on 3rd Oct 2019

This is a great mouthpiece. It’s very free blowing and slots well throughout the range of the horn. Won’t be the first mouthpiece I buy from ACB!

Modern blank
Written by Brad Niemi on 7th Sep 2019

I have the Lead 1.5 in the Modern blank, recently purchased. For me, it’s an excellent commercial/lead mouthpiece, somewhat similar to the Schilke 14a4a, but the rim feels slightly more “cushioned.” I’ve been using a GR Carl Fischer JazzRockstar, the Lead 1.5 edges it out, for me. If you’re a commercial player, (not a young developing student), this one might be a good choice for you. AS USUAL, EXCELLENT customer service from all the guys at ACB!

Written by Bobby Kellam on 18th Aug 2019

Excellent piece. Always great products from ACB.

review tot Mac 5B
Written by Terry Allen on 17th Jul 2019

Outstanding craftsman ship. Like it lots! Highly recommend working with ACB for MPC needs. While I have not purchased a horn from ACB, I am confident their service would be just as outstanding. I would not hesitate.

Mouthpiece review
Written by Timothy Moke on 2nd Jul 2019

Worth checking out all the ABC mouthpieces. The custom workmanship is very accurate. The customer service is top notch. The variety of rim shapes, back bores, and mouthpiece blanks is excellent. IMHO every trumpeter should possess a regular trumpet mouthpiece and aa matching FX short shank trumpet mouthpiece for a soft mellow flügel-like sound. Highly recommend!

Custom Mouthpiece
Written by Peter M on 13th Jun 2019

I can’t say enough about the craftsmanship of the custom slug mouthpiece Josh and I collaborated on. I play an Adams A4 and wanted it flush with the receiver and wanted more power to my sound. Josh took my current mouthpiece main and deepened the cup slightly (he responded quickly to my inquiry and kept in touch until the right specifications where met) and made it exactly how I wanted it. I know have the warmth and power I was lacking without any harsh reduction in range. I can’t say enough about the customer service, hard work, and 5 star craftsmanship. If your looking for a mouthpiece stop right now your search is over!

Written by Robert Moore on 9th Jun 2019

Wow! I love this mouthpiece. The rim is perfectly comfortable for my embouchure. It has a huge sound with such little effort. I can play without consciously manipulating the notes to find the sound I want which is exactly what you want in a mouthpiece. I am also finding that articulation is clearer and crisper compared to my previous mouthpiece. This piece was recommended to me by Josh from ACB after I enquired via email and he was bang on. Thank you.

MV 3C mouthpiece
Written by Peter Clarke on 7th May 2019

Best mouthpiece I've ever used, hands down! Articulation, range, sound, stamina. I thought my Giardinelli 3C was performing just fine, but wondered if something might be a little better. Beyond my highest expectations!

Mouthpiece safari is over!
Written by Bob Miller on 4th May 2019

I picked up several different cup sizes for different purposes, and they all seem to do the job very nicely. 1.25CS replaced my Monette B2S3 Prana Resonance, which was great, but just not for me. 1.25C/CB are great all around mouthpieces, but a bit deeper. 1.25CDS would have to be my go to for upper register playing. No too shallow that I bottom out or lose the lower register. I pretty much have all bases covered with these on hand. Great mouthpieces!

Written by Kevin Failoni on 21st Apr 2019

Wonderful mouthpiece

Written by Pete Carroll on 9th Feb 2019

In recent years I had been struggling between two mouthpieces for different applications. Both had their advantages and disadvantages. Just a few weeks ago, I scheduled an appointment at ACB to experiment with the mouthpiece collection. Kyle and Jon took the time to explain the different designs and give feedback on my sound production. After only 45 minutes, I found the most versatile and comfortable mouthpiece I've played to date...the 3S. Making such a quick decision worried me a bit. But, I must say that the transition has been smooth and I am pleased beyond expectations with this purchase. My next move??? An Adam's A4 to match??? Time to make another appointment!!!! Thank you ACB.

“Standard Series” 3C, standard blank. I have played this mouthpiece off and on since Austin Custom Brass’ first year in business. Since then, I have learned a lot and developed a lot as a trumpet player, and I wanted to contribute my current thoughts and experiences with this mouthpiece. I am a middle school band director and not the world’s greatest trumpet player, but I hope that my semi-professional perspective may benefit other semi-professionals considering this mouthpiece. The obvious thing to do is to compare it to the current (2018) Bach 3C. I say “current” because Bach changes their designs about every decade. I think the most significant difference, and the most compelling reason why I prefer the ACB 3C, is the rim. The current Bach rim is fat, more similar to Trent’s MV3C. The ACB 3C rim is less fat, and feels much more like my current Bach 1C rim (I am talking rim contour, not cup diameter… I did not say the ACB 3C is as big as a 1C). Some people may prefer the fatter rim, but I find that my flexibility is much, much better on the ACB 3C. I also find it easier to execute soft entrances. The tone is similar enough to “the Bach sound” that you could easily blend in a section of people playing Bach equipment. This is not an unconventional mouthpiece. I find the tone of the ACB slightly more full, like it has slightly more cup volume. I don’t know if it actually does or not, I am just speaking to what I hear. ACB offers a choice of several blanks, and they matter. They make a significant difference, so much so that if you find an ACB piece you really dig, you should order it in a few different blanks to see which one fits you and your music the best. One will definitely stand out. The tone will be slightly different, in that you will hear different proportions of the overtones. For example, the Traditional blank has slightly more emphasis on the higher overtones than the Standard blank, and so the Traditional blank sounds slightly more like a Bach mouthpiece. The biggest difference made by the blanks is the response, though. They just blow or feel differently. My preference is the Standard blank. I hesitate to comment on inner diameter / size. “Does it feel like the same size as a Bach 3C?” It is not that simple. Because the rim is so different, it hits my lips in a different way. So even though they may have the same diameter, there is much more to the story. And everyone is going to experience that differently because everyone’s lips are a different shape. If what you are really asking is, “will it feel the same on my lips as a Bach 3C?”, then the answer is no, but there is so much more to it than just diameter. Get size out of your head, it may be the least significant parameter when comparing these mouthpieces. As always, you just have to try it to see how it will work for you. The ACB 3C is superior for me than the Bach 3C in almost every way.

super comfortable
Written by J on 19th Aug 2018

As usual, ACB is killing it! Love the pieces. Comfy. Efficient. rich sound! What more could you want??!?!

ACB 5b traditional blank trumpet mouthpiece
Written by Thomas Chojnowski on 10th Aug 2018

Trent’s version of the Bach 5b trumpet mouthpiece has a much more comfortable rim and has a better tonal center then the original. My endurance on this piece is unbelievable.You have to learn to back off a little on this mouthpiece because it is much more efficient and it might get a little bright if you approach it like a traditional Bach 5b.Overall it’s an awesome mouthpiece. Thanks Trent for taking the time to make improvements to the traditional designs.

3C Modern Blank
Written by Stephen on 28th Jul 2018

Wasn't sure what to expect when ordering this product. Had heard great thing about Trent's pieces so I wanted to give one a try. Took me a day to adjust, but wow. Couldn't be happier about how I'm sounding. Has certainly helped me build my range of dynamics and articulation, as well as helping me find a more stable, consistent tone quality. This piece has also helped cut down on my warm-up time, while extending my endurance. A great fit for me! Thank you Trent!

ACB Lead 1
Written by Don Ables on 5th Jul 2018

The best way I can describe the LEAD 1, is the cup from the Yamaha Shew Lead and a rim similar to the Marcinkiewicz Shew 1. Whatever modifications Trent did to the throat/backbore make it play fantastic. It has more bite than the Yamaha, which helps with attacks, but is not uncomfortable at all. The rim is more flat than round, and if it were just a little wider would be the pinnacle of the Bobby Shew pieces in my opinion. I have play tested it for 3 days against the Shew Lead and Shew 1 and it is consistently slightly better than both. I see better improved attacks over the Yamaha and less of a harsh/brassy tone than the Marcinkiewicz. The rim diameter feels the exact same size as the Shew Lead to me and the cup appears to be the exact same shape/depth. If you play either the Shew 1 or Shew Lead and are looking to try something new, you owe it to yourself to try the Lead 1.

Custom mouthpiece
Written by Leslie on 12th Apr 2018

Chaps since delivery of my mouthpiece I haven’t been able to put it down. This is by far the best mp I’ve ever owned. Perfect slotting, pure, clean notes, warm sound, super comfortable and a dream tone. Oh and a great service. What more can you ask for :-)

The best Pieces Around
Written by Matt on 9th Mar 2018

This is now my second mouthpiece of the ACB line. Trent and Kyle were great at helping me get exactly what I was looking for this time around. There is no better place around for help and equipment.

3B modern blank
Written by Dave Mossing on 7th Mar 2018

What a great piece! Warm and rich sound with great response. It is really easy to play and even throughout the horn. I would highly recommend this mouthpiece! Great work Trent and company!

MV3C and MV3CS
Written by Jason Taylor on 4th Nov 2017

Both are awesome pieces! Rim is thick and comfortable. The MV3C has a darker sound but extremely responsive in upper and lower registers. The MV3CS is has a much brighter, richer sound! On a side note my customer service experience with these guys are second to none... They'll respond to you faster than you can type.

ACB H3 Trumpet Mouthpiece
Written by Jon Nickol on 2nd Nov 2017

I bought Trent's H3 trumpet mp and couldn't be more happier with it. The rim is extremely comfortable and I love the tone I get with it. I got it in the vintage blank which gives it a cool retro look also. I can highly recommend this quality piece!

Mouthpiece Review
Written by Mark Rapp on 23rd May 2017

Super fast customer response time and product delivery! The mouthpiece is solid, feels insanely comfortable and sounds amazing. It centers the pitch, the tone is incredible and projection is great. I could not be more pleased. Austin Custom Brass is setting a new standard in service and quality.

Always Great stuff from ACB
Written by J on 18th May 2017

Just got the 1.5R - super rich sound but easy to play. Comfortable rim with inner bite. Very nice guys!

Extremely Impressed
Written by Aaron on 14th May 2017

This mouthpiece is great. It's top heavy, and has a much brighter than my previous mouthpiece (a plastic topped ACB). I'm very satisfied with how this came, I asked them to cut it for a Reeve's sleeve and it was given a very clean cut. It took a while for it to come (~7 weeks), but it was well worth the wait. Thank you Austin Custom Brass for the amazing mouthpiece.

Written by Andy Cormier on 8th May 2017

After 27 years of playing a Monette B1-2 mouthpiece (a VERY LARGE orchestral piece), I made the switch to a 1.25CS. I decided on the change, because I felt I was 'falling into' my mouthpiece, the more I practiced and challenged my range. I've put 2 solid weeks on this mouthpiece, and I can honestly say it feels GREAT. It has the same stable feel that my Monette had. The sound I get is slightly brighter, but well balanced. The response is also awesome! On the efficiency of this mouthpiece: I can now play a daily amount that would have previously killed my chops. Now, I'm going and going, and no worse for wear the next day! I can't wait to see where my playing goes with this piece as my "home base". Thanks Trent for all the knowledge & help in choosing!

3c modern blank
Written by Bob Kellam on 5th Apr 2017

Excellent piece. Great guys to deal with.

Written by Andy Tichenor on 23rd Mar 2017

What a great mouthpiece! The standard ACB 3C model has an incredibly comfortable rim and the sound is full and resonant. As advertised, this will make for a great all around mouthpiece. I'm very happy I added this one to my mouthpiece arsenal!

Great mouthpieces
Written by Todd Jenkins on 14th Feb 2017

I play three Austin Brass mouthpieces: a 1.5cs on my Bb and C, a 1.5CMDF on my flugel and a 7m on my piccolo. Before discovering Austin about eighteen months ago, I had played another brand of mouthpieces for more than 15 years, but have not looked back since switching. I find my Austin mouthpieces to be well-made, comfortable, responsive and stylish. Whether I am in the pit, working with students, or playing in church or an orchestra, Austin mouthpieces help produce the sound I am looking for. Each time I have ordered a mouthpiece, I have emailed the shop with questions. I have been very pleased with the responses I have gotten to each of my questions. I have also been pleased with the speed of service I have experienced from Austin Custom Brass. I know the shop is incredibly busy, but they have answered my emails and shipped my merchandise quickly and professionally. I will most definitely be purchasing more equipment from ACB in the future and often recommend the shop to my friends.

Lead 1
Written by Patrick McKenzie on 3rd Feb 2017

Just to give you a refresher, I was the guy who had a show in Worcester and was in desperate need for a lead piece and I thought you were located in Texas! I purchased the lead as a quick fix became I was struggling on the piece I had in my case! After consulting with you, you had me try a few pieces and I settled on the Lead 1! I was thoroughly surprised at the sound I got but what also caught my ears were the compliments from the cast! They could hear a difference in my sound too! As soon as I'm done with the Northeast leg of this tour, I plan on consulting with you again for, a flugelhorn piece and perhaps I could get this lead piece in a V-cup! Great job Trent and it was pleasure to finally meet you in person!

Awesome all arounder.
Written by Mario Beaulieu on 2nd Dec 2016

I have the MV3C and the MV3L. Both have a great sound and are really easy to play.

Great Mouthpiece
Written by Ben on 29th Nov 2016

I had used a vintage Bach 1X for years and decided to go back to that size. I had misplaced my favorite and, at Josh's suggestion, ordered the ACB New York 1 in a Bach-style blank. It feels exactly as I remember and plays great. FIt and finish are superb and intonation is spot-on. I have always been totally satisfied with my purchases from Austin Custom Brass and this mouthpiece is no exception. Thanks, Trent and Josh!

Written by Peter Orne on 26th Nov 2016

I don't dwell too much on gear, but I recently test drove half a dozen mouthpieces at Austin Custom Brass in Reading, Mass., and discovered a beautiful Austin 3B that has revolutionized my sound, bringing new power, depth, and complexity to my mid-range improvising. This is one beautiful mouthpiece.

ACB's best kept secret
Written by undefined on 27th Oct 2016

I've been playing the Cee Bear now for 2 month and the more I use it and the more I compare it to other mouthpieces, the more I like it. It is extremely easy and fast responding, making it much easier for me to play more beautiful. The sound is full, but not dull and works great on my Bb and C trumpet. Even though it is a very large rim, I do not seem to sacrifice any notes in the upper register. My sound on Bb and C never sounded better. I mainly play on a local Orchestra and for that purpose it is the best I ever had.

Comfortable Rim with a fat pretty sound
Written by John Douglas on 20th Jul 2016

Outstanding craftsmanship, aesthetically pleasing, super comfortable, great fat dark warm sound and plays evenly throughout the range of the horn. Buy!

Traditional Blank 3C: purchased this first and is best 3C I have ever played. The rim is really secure and feels like a 3C Bach in terms of size. Sound is fantastic and has a real core and is equally as good sound wise as a Bach 3C but, it has fantastic playability with better slurs, articulation, intonation. It is a fantastic all around piece and better than any GR, Curry, Bach that I have owned. If you are looking for a better Bach 3C look no further. The Curry 3C. is good as well but it feels much bigger and more like my Bach 1 1/2C than a Bach 3C. I have been searching for a while for the feel of the modern Bach 3C with excellent sound and better playing characteristics and this is it! Standard Blank 3B: purchased this after the 3C as I liked the 3C so much. This is a great piece too. Sound is warmer and darker, articulations and slurring not quite as easy as the ACB 3C for me but still fantastic and much better than a Bach 3C still. Not sure which will become my main piece yet between the 3B and 3C from ACB;I am thinking it will be the 3B unless endurance and/or a slightly more brilliant sound is required and then it will be the 3C. It would be interesting to compare blanks for the same piece - my 3C is in traditional and the 3B in standard - I think I prefer the traditional slightly for looks and it is slightly heavier and slotting feels a tiny bit more secure on the 3C (but this could be the cup rather than blank so hard to say).

Some detail oriented mpc construction

Trent makes some ridiculously good mouthpieces. He's either a genius or completely lottery lucky on mouthpiece designs. His 1.25Orch model is to die for. Try it for yourself

Austin Custom Brass Mouthpieces are Amazing!
Written by Greg Plough on 31st Aug 2015

I've been playing ACB mouthpieces for a couple of years. I play XL bore horns (.469, and .470). I started with the ACB Fabrication 5, and liked it so much that I also ordered the ACB Standard 3DS...same rim, shallower cup...for a brighter sound. Both mouthpieces not only provided the sound I was looking for, but are very comfortable, and they also helped with endurance and flexibility. Fast forward to now, and due to some medication I have to take, my chops have reverted to needing a smaller diameter mouthpiece. I pulled out a few of my older mouthpieces from that time in the past when I played smaller diameter pieces, and discovered that the Marcinkiewicz 5 I played for many years was about the right size, but didn't provide the same sound, endurance, and flexibility. I got in touch with Scott Philbrick, who helped me settle on the 7M, and it turns out to be an awesome mouthpiece for me. The endurance is back, and I'm working on the flexibility.I get a rich, full sound from the piece...and it can really light up when pushed. Bravo Trent Austin and Austin Custom Brass!

GREAT commercial mpce
Written by undefined on 29th Jun 2015

Recently bought the ACB lead 1.5. For me, GREAT mouthpiece. Just the right blend of brightness, flexibility and projection. Plus Trent is a great guy to do business with. And because he is a monster player himself, he knows what works, even though that can be subjective.

Very comfortable piece!!
Written by Vince Beard on 24th Jun 2015

First of all Nick is a great guy! He was very patient and knowledgeable about not only the ACB gear, but everything in the store. I have been using the ACB 3CS modern blank mouthpiece for about 2 weeks. It has a very round sound and doesn't bite into my chops when playing for long periods.

Great commercial/lead mpce....
Written by Brad Niemi on 24th Jun 2015 least for me; mouthpieces of course are very subjective. I have previously used Schilke 14a4a, and more recently Monette LT BL. For me, the ACB Lead 1.5 gives me a bright sound, very good flexibility, that really cuts over the amps in the 13 piece funk/r&b band I work with. Plus, Trent is a great guy to do business with!

Great Jazz mouthpiece
Written by Alan Phillips on 17th Apr 2015

As a military musician I have to be as versatile as possible. I spoke with Trent last week about ordering a goldplated mouthpiece. He was able to get it to me with a quick turnaround. Top notch customer service. This mouthpiece plays so well my best friend purchased the same one with the same experience. Bravo to Trent and his team.

I have several of Trent's mouthpieces, most with a 3 rim. I personally prefer a mouthpiece that is free blowing and full sounding. Trent's mouthpieces do just that.

The "S" in 3CS must mean super!
Written by Ray Callender on 23rd Mar 2015

I've given Trent's 3C mouthpiece a 5 star review in the past and thought I'd do the same for the 3CS that I'm currently playing. I've been playing his 3CS for quite some time now and recently purchased one in the modern blank, which is a perfect match for my Martin Committee and Schilke HC2. It's quite simply the most comfortable and most responsive 3C type mouthpiece I've ever played with a fat, warm core to the sound. It's just a super efficient design that sounds great, what else do you need in a mouthpiece! Thanks so much for all the great gear you've made available to the trumpet world, keep up the great work Trent!

Great comfortable mouthpiece
Written by Tom Romano on 9th Mar 2015

Trent and his staff were great. They let me demo numerous mouthpieces and gave their opinion of my sound on each. Couldn't decide between 2 different mouthpieces so I bought both. They play extremely well, are very comfortable and fatigue no longer exists.

Found my mouthpiece
Written by Jon on 4th Mar 2015

Trent made a custom mouthpiece for me and I couldn't be happier with it. I've been playing on it for a year now and felt and heard the difference almost immediately. I got exactly what I asked for and I appreciate the work Trent did on it. Thanks!

Best Lead Piece on the Market!
Written by undefined on 10th Feb 2014

About a year ago, I switched to the ACB Lead 1. I have virtually played every brand on the market over the past 20 years and nothing has helped secure my playing like the Lead 1. The sound, articulation and projection is second to none. Trent is not only a first class musician but also a first class gentleman and businessman. Kudos to making equipment that works with you to maximize the musician within!

Great Mouthieces
Written by Victor L Sacino on 21st Feb 2013

The other day when I was practicing, I used one of my mouthpieces ( I have a lot, Lol) Well , when I picked up my Slug 3CS mouthpiece, the blow was so easy. If you never tried one, do yourself a favor & pick up one of Trent's mouthpieces. I am sure it would not be your last.

My new sound...
Written by Mike Giannetta on 20th Feb 2013

...couldn't be possible without my new ACB 3CS mouthpiece! When I tried it out I felt it right away! It was like I found the missing "piece" (pun intended) to my sound. Flexibity, articulation, sound, speakability in all registers, ease of's all there. So impressed with Trent's products, and SO happy with my new mouthpiece!

Perhaps the best 1 1/2 C I've ever played.
Written by Jake on 25th Jan 2013

Trent's 1 1/2 C is really a special mouthpiece. Incredibly comfy rim - I never along well with the Bach 1 1/2 C, the rim felt thin and sharp, didn't give me any support. This one feels great and would be a great "next step" for a 3C player - it feels very accessible to those who are used to slightly smaller diameters. What's more, the blow is extremely efficient - my endurance is much better on this than on any other 1 1/2 C I've played before. The confusing thing is that it actually sounds bigger and darker than these less efficient pieces. The core is huge and warm at medium to soft volumes, but it can light up and project just fine when you give it a little gas. I seem to have a much wider tonal palette on this mouthpiece than comparable ones from other manufacturers. Don't be afraid of this piece if diameters larger than a traditional 3 have turned you off before! This barely feels bigger and loses no efficiency in the process. GREAT legit mouthpiece.

3DS - Great compliment to the ACB 5
Written by GregPlo on 8th Jan 2013

I previously reviewed the ACB 5, and in that review, you will see me asking about a slightly shallower mouthpiece. Trent recommended the 3DS, and I have to say his recommendation was spot on. The 3DS feels almost identical at the rim, and even though the cup is slightly shallower than the ACB 5, the undercut is such that I have no trouble keeping the lips buzzing even when I'm tired, unless I'm just fully worn out. I find this mouthpiece works great for just about any venue except pure legit...and that's when I pull out the ACB 5. Trent...thank you for making great products, and for your expertise in choosing the right mouthpiece!

Great 3C!
Written by Chad McCullough on 12th Dec 2012

This is a really great mouthpiece! It's one of the first 3C's I've played that just feels right... totally worth owning!

Fantastic mouthpieces!
Written by J A Trombetta on 24th Oct 2012

These are incredible playing mouthpieces designed and offered by one of my favorite trumpet players and one of the most knowledgable people in this biz. Since first working with Trent some years ago I knew he was a special player with genuine well-researched insights, and obviously a great guy. The standard blank is a real hit with me. The quality of manufacturing, fit and finish are on par with the finest equipment available. Whether you are looking for your "daily driver" everyday mpc, or something special to fit a new horn, Trent offers the full spectrum of mouthpieces, and you can absolutely trust him to point you toward the best choices for you. Why? Whatever facet of trumpet playing you are involved with, Trent's done that, and on a very high level!

The best 3C size mouthpiece on the market, period!!!!!!!
Written by Ray Callender on 31st Jul 2012

Trent's own description of the ACB 3C mouthpiece is dead on: I have never played a 3C like it! I've played GR, Monette, Curry, Bach, etc. mouthpieces in the past and hands down this is best I've ever played. The sound it produces has such a warm, buttery core with sparkling overtones and it just feels "right" on your chops. I love the look of the mouthpiece too--I chose the standard ACB blank which has a real hip Al Cass-inspired look to it (that extra weight around the rim really adds weight to the sound too). You owe it to yourself as a trumpeter to try one of Trent's brilliant mouthpieces--you'll be glad you did!!!!

Ta-Lead: Awesome!
Written by M. Oleson on 15th Feb 2012

Have been playing on an ACB TA-Lead mouthpiece for a number of days now. This is the fourth mouthpiece purchased from Trent. The TA-Lead is great in big band applications as it has a very rich core (as all his mp's do) plus with the added sizzle when going above high C. I'm now spoiled as no other brand of mouthpiece will do...great work, Trent!

Austin Custom Brass TA2
Written by Rob R. on 15th Nov 2010

A quick review of the TA2: wow Now for a more complete review. I really enjoyed it on my gig last night. It was so comfortable and easy to play. I also had to back of my mic a little bit. So much core and center to the sound that it just flew out the bell. It works so well with my 43 its ridiculous. Lots of brilliance to the sound without becoming harsh, especially in the middle and lower registers. It sounds cliche, but as someone who plays mostly bigger pieces for everything else, I've found my perfect lead/ commercial piece! Thanks Trent!
