Here's a rendering of the new FX series  and they are available now!


This is an extension over my very popular TF series... people have wanted an even deeper, darker, richer, and thicker hybrid sound. This will be it! The extra short but still standard gapping trumpet shank will help the pitch on these. Very excited to offer this to clients. Any rim in the ACB line is available. Get yours today!

Everything and more !!

Reached out to my pal Troy Dowding to have a discussion about a mouthpiece that would best emulate the mellow tone of a flugelhorn without having to switch to a flugelhorn. The ACB FX Hybrid came up immediately from Troy. I checked out the video on the ACB site and wow... these pieces are every bit as mellow as the DEMO reveals. Very deep cup, very free blowing, almost no resistance and man does it mellow out any horn. I have an old Conn 16B Director as well as my main RBT Benzina custom horn, and they are both like butter with this mouthpiece. If you are looking for that mellow flugelhorn sound out of your trumpets, look no further.

First off the customer service was fantastic! I purchased the 3cs hybrid fx mouthpiece and loved it as soon as i put it in my trumpet. Super easy to play and extremely comfortable, the sound that it gives you is awesome . I would recommend trying one of these hybrid fx, dont think about it, just buy one, you will be happy you did!

Great Hybrid Mouthpiece!

This is a great hybrid mouthpiece if you're looking to mellow out your sound without having to break out your flugel every time. Also works extremely well with a pocket trumpet! Highly recommended.

I bought this to use on a gig I've been doing where room is really small and I need to take the edge off the trumpet. This piece is where it's at! Gives me a great fluffy tone and warm rounded sound. It is DEEP though so anything above an A you really gotta push. But this piece is EXACTLY what you need if you're looking for a warm round flugel sound in Bb. Love this piece!!!!

Incredible Feel and Sound

I've been using the MV3c-Fx mouthpiece with my Adams A4 for the last month and can't say enough great things about the versatility of this piece. It literally transforms my horn into something completely different sonically, and feels great on the chops as well. Having played on the same two mouthpieces for the last decade I typically don't like to change my setup but this piece is a permanent addition to my gigging arsenal from now on. Thanks so much for the hard work and great customer service as always Trent! Can't wait to pick up another one soon!
