Mouthpieces

"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!" -Trent Austin
