 Grabner HiTech

Soprano Clarinet Mouthpiece 


This mouthpiece  is based on one of my three original soprano clarinet mouthpiece designs. It replaces the CXZ_K11*. The CXZ_K11* was my first big "hit" and I still regard it with a lot of affection.

It is a free-blowing mouthpiece, with a full, warm, mellow tone. It has plenty of projection and very fast response.

I have sold thousands of mouthpieces based on this design. 

A 440.

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

This mouthpiece was 3D printed on a HP Jet Fusion 3D printer using a long-lasting, very resiliant material. Drop it as many times as you want, it does not chip or break!

The S1C Mouthpiece is $225.00 each, $250.00 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.
