Mouthpiece Tops From ACB!

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!

Pick up one of our ACB mouthpiece tops and match it with a ton of backbore options! All ACB tops come standard with #27 throat and Warburton threads for greatest compatibility.

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.

"I've been playing the Cee Bear now for 2 months 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 in a local Orchestra and for that purpose it is the best I ever had." -a satisfied customer

 

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 manufacturers' "cookie cutter" rim contoured 1 1/2's.
  • 1.5 CB: Similar to the 1.25 CB with my ACB 1 1/2C rim

"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" -a satisfied customer

 

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: https://www.austincustombrass.biz/austin-custom-brass-mv-3c-special-mouthpieces/
  • 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.

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

 

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 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!

"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... 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!" -Ray

 

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!

"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!" -a satisfied customer

 

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.

"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 off 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 [Bach Stradivarius] 43 it's 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!" -Rob

 

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 backbore I'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:

1.5 Lead top ACB
Written by Patrick Gormandy on 3rd Mar 2020

Trent really nailed this mouthpiece. If you are looking for something to replace your 14a4a, this is it.

Quality piece!
Written by derek limback on 18th Feb 2019

I replaced my 30 year old Bach 1.5C gold plated mouthpiece with this top (1.5C) also in gold plate. It is a beautiful piece that feels great on the face! The rim is more comfortable than my old Bach and with the backbore I got with my 3DS, it plays very well. Endurance and range seem better on this set up. I'm loving my ACB custom mouthpieces! Can't wait to try more!

ACB Mouthpiece
Written by Scotty Welch on 21st Nov 2018

I have been using ACB mouthpieces for 12 years, trumpet, flugelhorn,and cornet. I find them comfortable, efficient, and spot on intonation! I especially like the convenience of changing tops and bottoms for different situations and horns!

3CS in Acrylic Top
Written by Rick Pierce on 31st Oct 2018

I was a little bit suspect about trying a mouthpiece with an acrylic top as I had always played on metal. I was informed that they only had this top in acrylic and decided to try it. My original thought was to use this for a more commercial sound (I don't like shallow mouthpieces). After playing the CS design, I'm using this as my main piece. I love the sound and response in all registers. The acrylic material is extremely comfortable and not subject to temperature.

4/5
MV3C
Written by Blaine on 2nd Dec 2017

Just a come back player after taking 20 years off. After trying a couple other tops on my own and even purchasing the old Warburton piece I used back in the college jazz band days I decided to try the MV3C. Love how this one feels and it is has a graeat full sound. I am still working on my endurance after 20 years off but my search for the right top is over. Thanks Josh! I liked the rim so much I aslo added an MV3L that I just recieved and it has a very nice sound in the upper registers. I pair both the MO and the S backbores with the MV3C and the S with the MV3L with my early trial on it.

5/5
MV3C top, MO bottom
Written by Lionel Emde on 16th Feb 2017

This is a great mouthpiece. Full rich tone, easy attacks, comfortable rim, it's a lot of fun to play. I can see why these old 3C's command a high price, if they play like this replica. I had it cut for sleeves on the shank, so as to dial things in - it sounds gorgeous on my Calicchio. Good work, indeed!

TA3-MV3C
Written by Bill Wasserman on 10th Jan 2017

Once again, I am in awe of Trent Austin's ability to exceed my expectations with his advice, expertise and the excellence of his products. I asked about combining the wonderful rim of his new Gen II TA3 mouthpiece with a deeper cup. He arranged a marriage with his MV3C cup and not only do I have a comfortable 3 size rim but I have the beautiful sound and efficiency of that classic cup. When Trent suggested I try it on Piccolo, I scoffed!! Then I found I could play the C-A with that soft quiet piccolo sound I've never been able to get with smaller pieces. Talk to Trent! Tell him what you want! You wont be sorry!

5/5
Very good balanced
Written by Magnus Bohlin on 23rd Nov 2016

I play my leadjob on the lead 1 pice with A2 backbore. After a while I ordered a Lead 1 top to check if I could optimize the backbore setting. After testning my 11 warburton backbores on it the A2 still was the best, my compliments for having made a very good balanced mouthpiece! Instead I ordered a slug A2 backbore to fit the top...

5/5
Perfect Balance
Written by Rich on 23rd Feb 2016

Perfect balance of comfort, articulation, sound and versatility, it works with a MO or MT back bore, especially well with the heavier back bore. (10.5 C)

Excellent Mouthpiece and service
Written by undefined on 16th Jul 2015

The ACB line of mouthpieces are the easiest playing and most comfortable for me. Knowledge of the products and service and followup are outstanding.
