We offer 4 different backbore sizes which can be ordered with any of our standard range of mouthpieces.
#1 Lead Our narrowest backbore which works perfectly with the HC and ES Lead cups to give high compression without feeling too restrictive.
#2 Lead / Commercial A slightly more open backbore than the #1 the #2 backbore will work well in a variety of commercial situations where a felxibility of tone and attacks is important. This backbore will also work well with our M cups for players seeking a little more resistance without going shallower (special order)
#3 Commercial / Chamber Perfect for all round playing including pit work, light orchestral and jazz solo playing, the #3 is designed to balance perfectly with the our M cups . This backbore will also work well with our C cups for players seeking a little more resistance without going shallower (special order)
#4 Symphony Our "legit" backbore comparable to a standard Bach mouthpiece backbore.
