i recently bought an f tuba and i need a new, tiny mouthpiece. i'm used to playing on a big gold Monette Prana, and a superheavy Jet tone on a BBb tuba. Man are they big, but the small mouthpiece thing is kinda confusing. does anyone know where to get/make an adapter? could you recommend some good tuba mouthpieces for f tubas? what do you think about dennis wick, or perantucci? thanks again guys, and gals,
