Grabner HiTech

Bass Clarinet Mouthpiece 


This, and the B4C, are the best bass clarinet mouthpieces I have ever made, including the Zinner based models. All aspects of design, manufacture, and testing are totally under my control. Buy one while they are available.

With a tip opening of 1.80, this mouthpiece has plenty of tone! Similar to the B4C, but with a more open tip, this mouthpiece allows you to really bring out the lowest register.

This mouthpiece is based on my Virtuoso Bass design, which has been very popular. In two years, I sold hundreds of them.


Plays well with a Vandoren Bass Clarinet V12 #3 or #3 1/2 reed.

They also play extremely well with the Legere American Cut Tenor Sax reed. I have them for sale below, so that you can try them with the mouthpiece

The future is here

This mouthpiece was digitally designed and manufactured to the most precise technical standards. It has been hand-finished, adjusted, and play tested for optimum performance.

The B4M Mouthpiece is $400.00 each.

Terms are the same - try one or more for a week, send back what you don't want to keep for a quick refund.
