*Please note, this model was originally designed with the FR rim profile, and is now available with the RR and CR rims*
The 81M is comparable to a Bach 5 inner diameter. This mouthpiece has a medium V cup design. A fat, slightly rounded rim with the high point pretty close to the center of the rim. (Ever so slightly toward the inside the of the rim.) This mouthpiece has more resistance than the old Jet-tones providing more endurance, better projection and an easier high end. The sound is full and resonant from the very bottom of the range to the top. The back-bore is matched perfectly to the top to give you a balanced mouthpiece.
Available Rim Profiles:
81M: 0.6453 inner diameter measured at 0.030" 0.1410 throat 28 drill 1.0801 outer diameter
