Mouthpieces
Tenor
I've been playing and endorsing Francois Louis tenor mouthpieces since 1992. My model is a solid silver and was hand made by Francois Louis in Belgium. Tip opening is approx. 132.  I use  the ligature that came with the mouthpiece or a “Ligaphone” Universal ligature.

I'm using a Beechler White Diamond "Custom" and/or the "Phil Sobel" model
Soprano
Vandoren S35
Vandoren V16-S7 for classical

Ligatures
I use and endorse Ligaphone ligatures on all my horns. They really help even out the response in all the registers, and at all volume levels. This is the best ligature I have ever played.
