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. 
A 440.

Although it shares features of the S4M mouthpiece, this mouthpiece is designed specifically for the Legere European Cut reed. It plays especially well with the  #3.50 and #3.75 strengths. The reeds fit the facing properly (or vice versa). Below, you may order a sample reed with the mouthpiece.

Customer Comments:

.... I switched to Legere earlier this year so I love how they pair with the Euro Signatures, really amazing combination........

.......the S4M-LE is probably the best intonation Iíve ever experienced on my clarinet, and Iíve tried quite a few (mouthpieces)......

....the S4M-LE overall just really brings the intonation together in a really beautiful way.  It checked all the boxes for me.......

....Walter, I forgot to update you. The mouthpiece arrived last week and I just love it! Great work!.........

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 S4M-LE Mouthpiece is $250.

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