I have been playing an SM3.5 on a large bore instrument for the last four years, and couldn't be happier with it. Recently, having changed from a Yamaha 642 to a Prestige, I was without an instrument for a month and had to borrow an instrument from the band. Since the loaner was a small bore Yamaha 321, I couldn't use my usual mouthpiece and, having recently given my small shank SM4 test mouthpiece to a student, had to make do with some small shank trombone mouthpieces I had around the house - Bach 6-1/2, Schilke 51B etc. I was frustrated and upset, and thought the poor results were all due to the instrument that I had - tiny tight sound, poor intonation and rigid nuance and flexibility.

Last weekend, a student lent me his small shank SM4B, and it made a HUGE difference. It was like watching the sun come out after a rain storm - suddenly the instrument felt "right". The overall intonation was much improved and inherent defects were much more manageable. The sound was fuller and more stable in both the high and low registers, and dynamics, vibrato and articulation were much more flexible. Playing was once again a pleasure, - all thanks to the mouthpiece.

Several of my students play your mouthpiece on similar instruments, and they have all experienced the same leap of quality when they started playing with the new MP. I don't like to force students to play a particular mouthpiece, so usually we take some time testing mouthpieces and comparing your mouthpieces with whatever the student was using before. Hands down, your mouthpieces have always been the very obvious choice, and now that I've gone through the experience again myself, I can reaffirm that your SM mouthpieces are an excellent choice for both small and large bore euphs, in both piston and rotary valve models.

Thanks for your continuing research and for making these mouthpieces available through the website.
