Karl Hammond Jay Friedman Signature Trombone Mouthpiece

The Karl Hammond Design Jay Friedman trombone mouthpieces are the result of a collaboration between Karl Hammond Design and Jay Friedman, principal trombone of the Chicago Symphony Orchestra.

The F1 model is based on the Bach 3G, but with a medium rounded rim, more funnel shaped cup and slightly narrower throat for more focus in the upper register. Produces a large, warm modern symphonic sound, but requires a strong, focused embouchure and air stream to produce the desired center for 1st and 2nd large orchestra tenor trombone parts. Compares to Hammond 10 rim. 

The F2 is the same mouthpiece design as the F1, but with a number 11 rim (similar to the Bach 4G).
