Selling a Greg Black 4.5GSW regular weight mouthpiece in very good condition. This is similar to the 4.5GS with a little more depth to the cup and the #1 backbore. I believe the "W" marking is because this is the modification Colin Williams had designed. Great condition still after a couple months use, just with some marks on the shank. Pictures will be added here later.

Here's the description off Greg's website: This series was born from players requesting a cup depth slightly deeper than the standard ‘GS’ cup, yet not as deep as the ‘GSD’, paired with a custom backbore Greg designed providing the player a rich tone color while maintaining clarity in the upper register.
