"It is amazing how much a mouthpiece can change the sound of a horn. When I first played on this mouthpiece, the quality of sound on my old cornet went from strident to lush, warm and mellow. These are the characteristics you want on a cornet. Plus, the design of the rim is incredibly comfortable. This is a stellar mouthpiece." -Mark Rapp


Introducing the new ACB Cornet Mouthpieces!



The five cup depths in the ACB Cornet line:


"D" Cup: shallow bowl which is great for piccolo and trad jazz


"C" Cup: good for all-around and even piccolo


"B" Cup: a nice rich solo cornet sound and ensemble piece for brass band performance


"Hybrid TF" Cup: great for solo work and jazz, as well as brass band


"A" Cup: an extremely deep, almost deep flugelhorn piece that produces an amazingly rich tone. This is a huge mouthpiece depth wise, but the sound it makes for a very strong player is glorious!


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

1 ¼ seriesthis 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".

Here's a recent review from one of our clients:

"Bought a TA2A, at the beginning of the year and being playing it for most of the time.
I've been playing British Brass Band music in Germany, Spain and USA for almost 40 years. Most of the time I used a Wick 4b, Bach 5 and Sparx 4. 3 years ago I moved to Scotland and found out that my sound was way too bright for British Brass Banding. Switched from a 4 cup to a 3 cup helped a little, but was not sufficient.
So beginning of 2014 I ordered a TA2A from Trent. I first was afraid that the rim would be too large and that my upper range would be lowered. However, I was very surprised how comfortable the rim felt and I was able to obtain my upper pretty much.
The Sound is extremely full and smooth, fitting perfectly into the REAL British Brass Sound.
Rim (regular blank) is extremely comfortable and gives lots of support even after my lips tired out.
I have tried a DW 3 RW (no letter) before - which this mouthpiece has been based on - and I sounded dead and dull, beside my upper register was very limited and the rim was very uncomfortable (for me).
Is this the perfect British Brass Band Cornet mouthpiece? Sound-wise I would say yes. The large V cup and wide open throat gives it that full and smooth sound you want in British Brass Banding. However, there is a price to pay: Air support and a decent embouchure."

    Great for doubling

    Posted by David on 11th Aug 2019

    Got the MV3CS C recommended by Josh to go with my doublers cornet. It is a really comfortable mouthpiece, has a great sound, and makes doubling much easier. The brushed finish looks sharp too, but insertion marks show up quickly. Very happy.

    Great piece. Does what I wanted ie: darkens the brilliance of my long-model cornet. Great for back benchers in lower registers.
