Symington 1 1/2G Zirconium bass trombone mouthpiece.

A great version of the classic 1 1/2G! So what does the Zirconium do? I feel it adds a lot of warmth to your sound. Response in soft dynamics is exceptional and it keeps that special warmth also in louder dynamics without getting covered. If you are looking for a classic 1 1/2 G sound, this is it!

Zirconium is also basically indestructible, so this mouthpiece will be with you for a lifetime!
