Bass Trombone Mouthpiece Giardinelli 1G. This is a later Giardinelli mouthpiece with the smaller engraving. It's a 1G, but it measures around 27mm, which feels like a size similar to a current, general 1.5, or perhaps slightly more compact. I liked it because it responded well without feeling small. I used tape on the shank to prevent scratches, so it's in good condition. I think it's become a more valuable brand than it was back then. Shipping may take 2-3 days.
