Very large cup, principally used by players having healthy,strong embouchures.
For players with good,natural embourchures. Rather large cup. Produces a full, mellow, sonorous tone. With larger "G"(17/64) throat and #420 backbore.
Symphonic model mouthpiece features the same cup and rim as No. 6.1/2A but with symphonic throat and backbore.
For players who prefer a medium-large cup to assure s large volume of tone. Rather shallow cup produces great brilliancy.
