Hello all, I play a Yamaha 14 A 4, and can't seem to find another one anywhere, They all are 14A 4A, are they now called 14C4 or something like that?, I need to get another one for a pocket trumpet I just bought, I don't get caught up in the mental mouthpiece game, been playing the 14A4 for 15 + years and a 3c bach flugel mouthpiece,...so looking for a yamaha 14A4 or something similar, thx much
