Grabner HiTech

Soprano Clarinet Mouthpiece


I am totally excited about this new mouthpiece. It is made totally by me, in my in-house printer farm. No other hands touch it, but mine, from inception to delivery. This gives me a control over the product that I have never had before.

With its larger chamber, and deeper baffle, this mouthpiece, has a warm, dark tone. It produces a very focused sound, yet
also projects well and posseses very fast response. 
A 440.

Plays well with a Vandoren V12 3 1/2 .

It alsoplays especially well with the Legere European Cut Reeds. The reeds fit the facing properly (or vice versa).

The future is here
