Hello guys. At the moment I play in a Yamaha Yep 321 with his common mouthpiece, a small shank yamaha 48. I've been 7 years with this euphonium and his standart mouthpiece. In fact I finished my professional studies with him here in Spain, but now I'm thinking of changing my mouthpiece. I would like to get a deeper sound, also in low register despite the fact that this is a non compensating euphonium. I was thinking about a SMB4U-X or a SM5, but I don't know if is good to take a large mouthpiece like these. Nowaday I'm 19. I started my euph studies at 7 and I've been since 11 with this euph and mouthpiece, so ¿what would you recommend me?
Thanks and regards.
