Match our V cup with your favorite ACB rim!

One of the first things I wanted to do in my mouthpiece series was to create a line of mouthpieces that mix comfortable modern rims with the GREAT sound and efficiency of the old Heim cup. The cup of our V series is similar to my TA-1 cup, except deeper. It produces an extremely warm sound with efficiency you would never think possible!

Each product listed will have the "V" cup matched with the rim you choose:

For example, if you select "3" in the drop down menu, you will get our 3 rim with the "V" cup shape.


Welcome to the NEW STANDARD!

"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 best tolerances in the industry!" -Trent Austin


Why a new standard line?   It's a simplified version of our previous standard line mouthpieces with a bunch of improvements over the past decade plus.  Lots of companies update their products annually and we feel like it’s time we finally updated our line with all of the amazing improvements we have been implementing over these 12+ years.   We've simplified the line a great deal and eliminated a lot of frankly confusing options (although anything can still be custom ordered in our legacy listing).  The introduction of our Custom Reserve  line showed us many things in terms of ease of stock and having products almost always available for you.This makes it easier for us to always have pieces in stock and also far easier for our dealers too!


The best part there's not going to be an increase in price for the customer. It seems like everything else is increasing in price, the ACB New Standard series will be still available at the same price as our current standard line.  This has taken us close to a year to work on and we are so excited to show you the fruits of our labor!

Most of our ACB mouthpieces are in stock in our selected preferred  blank.  This has been chosen by testing a great deal of options and we honestly feel these are the best blanks for the new line.  Of course  other ACB blanks are custom made to order and may not be in stock. Please note that almost every manufacturer measures in a slightly different place, so the comparison information sheet is for broad comparisons only.


Please note there are no returns on custom orders; gold plating is considered a custom order. 

1 Series mouthpieces: Similar to the Papa/00 in the Legacy series, the rim is .684".

1 ¼ series: this has a classic Bach Mt. Vernon 1-1/4C mouthpiece rim that's blended in the CAD program to our cups. The rim is .673".

1 ½ Series: this piece has a classic Bach Mt. Vernon 1-½ C mouthpiece rim that's blended in the CAD program to our cups. The rim is .668".

  • "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

2 Series rim (based on our ACB MV3C rim): this piece has a classic Bach Mt. Vernon 3C mouthpiece rim that's blended in the CAD program to our cups. The rim is .664".

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

3 Series mouthpieces: same rim as on my Legacy 3C, which is my take on a fantastic Bach 3C mouthpiece from the late 60's; I have never played a 3C like it.

4 Series rim (based on our ACB 3CS rim): the rim is comfortable, with an inner diameter of .650".

5 Series mouthpieces: 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 with a .644" inner diameter!

  • "I've given Trent's 3C mouthpiece a 5 star review in the past and thought I'd do the same for the 3CS (now the 4CS in our new standard line) 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


10 ½ series mouthpieces: while this is a fairly small diameter mouthpiece (.630") 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.

  •  "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

TA1 Series (designed for my own personal playing needs): While the TA1 is based on Clark Terry’s mouthpiece, I made a few alterations and improvements. Clark’s original rim design was VERY flat, so for the TA1 I modified the rim and cup to make it more accessible for today’s modern player. The TA1 rim is still flat, but not nearly as pronounced as on Clark’s mouthpiece. I increased the diameter of the piece as well, as the original was a tiny bit small for my taste. The inner diameter is .639".

    TA Lead V series trumpet mouthpiece

    Posted by Al on 15th Feb 2022

    Plays very well with more projection out of the bell - I hear less behind. Opened up a couple more notes above high C and easier to play. I do like the rim as more comfortable than my Bach 3S commercial. Found harder then the Bach to be precise in low notes under the staff, such as lowest A. Along with the mouthpiece I am using a KGU medium weight booster. I like that I can glissando and the top notes slot (I did have to adjust with my Jupiter XO 1600i leadpipe since as received, with this mouthpiece I had zero leadpipe gap. Made it so now about 1/16 inch so better slotting for me)

    Fantastic jazz mouthpiece!

    Posted by Bob Miller on 4th May 2019

    I picked up a 1.25C-V recently, and am very happy with the sound and feel of this mouthpiece. Not nearly as deep as a hybrid trumpet/flugel cup. Easy to get that dark rich sound without losing range or the overall core of your sound. Great mouthpiece!

    MV 3C V

    Posted by Michal on 25th Feb 2019

    What happened when mixing Austin's great MV 3C rim with Austin's amazing V series / TA-1 / Heim? Miracle for me! I looking for this sound, flexibility, and character a long time ago. Contrast sound between high, deep, sharp or soft is so easy now. Most perfect amplifier - when you play thin - the sound is like angel hair - when you play widely or deep; maybe human power is only one limitation. For me, this mouthpiece doesn't play soft - only allows play soft. Very silky and soft if you want. But on the other hand - you can take a saw. This V profile is a very strong motor. Efficient. Beware of bugs. Sorry for my English . ) Thank you, Austin, Chris ... M

    great mouthpiece

    Posted by Guillaume M. on 3rd Jun 2016

    I ordered the 3CV in modern blank. It took only 10 days to be shipped to Europe. About the mouthpiece: I am not an "old" trumpeter, but so far I was using a yamaha bobby Shew Jazz mouthpiece. What I can tell is that ACB one is really rim-comfortable (rim shape is softer), and plays great. I find it easier than the yamaha one (for me of course), and it sounds great ! Do not hesitate to try this out !

    I recently ordered a 3cv from Trent in a modern blank. It's extremely comfortable rim wise, and the sound is great. I was looking for something in-between my 3ctf and 3c. This is perfect! For any real Chet, Miles, or Clark fan out there this is a great mouthpiece for that sort of sound.

    Orchestral sound with a 3 rim

    Posted by Capt. Z on 2nd Apr 2015

    I just got the ACB 3CV a few days ago and already used it during my own rehearsals and band rehearsal. I personally prefer a nice full and warm sound and the 3CV does just that without sounding dull.
