For sale is a Wedge 101G large shank trombone mouthpiece that is practically brand new.  I have used the mouthpiece for a few months since buying it brand new directly from Wedge and it is just not exactly what I'm looking for.  This is a hybrid mouthpiece.  You can get a practically brand new mouthpiece for much less than what it retails for.  Check out my 100% positive feedback rating over the last 21 years and bid with confidence.  

From Wedge's website:

"The Wedge Hybrid mouthpiece was designed as an option for players who could not play on a metal mouthpiece, or who preferred to play on plastic despite its limitations. However, it has quickly become our most popular option, thanks to its outstanding comfort and sound."
