Close up of the 'business' end of the mouthpiece.
Extremely rare, French made metal mouthpiece. I've only seen one for tenor. These blanks are very similar to Florida era Super Tone Masters.
Modern Super Tone master re-cut for superior response and a more modern voice.
These have to be reworked inside as well due to very crude factory workmanship.
A close up of the tip rail and baffle work. Details like these result in a superior response and voicing of these mass produced mouthpieces.
