Grabner HiTech

Soprano Clarinet Mouthpiece



I am 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.

This mouthpiece has my most open tip, to 1.20.

Tunes to A 440.

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

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

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 S4MO Mouthpiece is $250.00 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.
