To be fair, I'm playing an ANCIENT Martin saxophone and this is a more modern piece, and it may be that the two were simply not meant for each other

The Rico Graftionite (I'll refer to it as RGM) mouthpieces have been a breakthough in inexpensive yet well constructed and designed pieces

They are affordable mouth pieces and seem to do a serviceable job job.

Quick and to the point - some people love this piece as much as $300-400 mouthpieces
