For Sale: Denis Wick/Steven Mead SM6U euphonium mouthpiece.
Gold plated, 25.40 mm cup, 6.30 mm rim, 6.66 mm throat, V type backbore, only played a few times, no insertion marks. Pics available. $150

I have one in the mid-sized shank for my B&H 3-valve comp, and another one with the small shank. Great mouthpiece! it is essentially a 6 1/2 AL with a deeper cup and better designed throat and backbore. It keeps the low register from being grainy, helps the middle register be more lyrical, and helps with security in the upper register. Yes, a great mouthpiece, indeed!
