Grabner HiTech 

Soprano Clarinet Mouthpiece 


            Big success at ClarinetFest2019!

This mouthpiece is an entirely a new design, and is the most daring mouthpiece I have created.

The mouthpiece chamber is hand-modified to create an equal balance between brillance and darkness, with a super fast response which will enhance your tonguing speed. I have wanted to do this design for years. Now I can finally produce it!

A 440.

Plays well with a Vandoren V12 # 3 1/2 or #4

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 optimal performance.

The S3M Mouthpiece is $390.00 each, $415.00 with Rovner 1R Ligature and Cap. Terms are the same - try one or more for a week, send back what you don't want to keep for a quick refund.
