My #1 selling mouthpiece at ACB!


ACB MV 3C  Special Trumpet Mouthpiece


I have often wondered why you see the eBay auctions of Bach Mount Vernon 3C mouthpieces sell routinely for $400 and more.  Is there something special and different to these pieces over a traditional 3c?  


Well... the answer I found out was  YES!


Check out the overlay below for a comparison of my standard  3C (in red)  to the ACB  MV  3C:



I am now offering this custom mouthpiece in my line for a lot of reasons but mostly because it sounds so great!   It is a bit bigger all-around (as seen in the overlay)  than the traditional 3C.  For me it feels a smidge smaller than a 1 1/2C.  I also put my MO  backbore (smaller symphonic shaped)  and a #26 throat in this piece.  The sound shape is tremendous and rich.


All non-standard blank ACB pieces are custom orders and take 4 weeks.

I will compare this piece to the Curry 3C., since I have been playing that for years and many people have one. The rims are basically the same -- my chops could not feel a difference, which is fine because it's a great rim. The inner diameter felt the same too. So if you like your Curry 3C., you will have a seamless transition to this MV 3C. The tone is very similar, but the ACB had more power / depth to the sound as I played above the staff. I wouldn't say the Curry gets "thin" above the staff necessarily, but it is thinner by comparison. The ACB, for me, had all the brilliance of the Curry plus a dark core underneath it. This can probably be attributed to the backbore Trent designed, but I don't know. This is coming from an amateur player. I am just a lowly middle school band director, not a pro player. Someone with better chops and more practice time could probably get a lot more out of this piece that I can. Bottom line: The MV3C is everything you love about your Curry 3C. but with more dark power / core to the sound.

MV 3C from Trent

I've played this piece for about 8 months now and love it. It's very comfortable, has wonderful tone quality on my Selmer Radial. I got the superslug blank. Couldn't ask for a better person to work with. Trent Rocks!!!
