Once regarded as the premiere mouthpieces for brass players, i.e., trumpet, trombone, and bass trombone, availability of GB mouthpieces are very scarce and often impossible to obtain.

The large selection of GB mouthpieces and its designs orginiated from the Giardinelli, NYC days. It was there that Bob Giardinelli designed the world reknowned Giardinelli Mouthpiece.

GB Mouthpieces incorporate the designs and specs of that of Giardinelli and Bach Mouthpieces.  All mouthpieces are outsourced and  manufactured by Warburton Musical Products, Fla.  Blanks are CNC made and then shipped to Greg Black where  “the finishing touches” are completed, i.e., stamping, backbore,cup tweaking, and buffing. Once this is completed, pieces are sent to either The BrassLab, Brooklyn, NY, or Stork Mouthpieces, Vermont for plating.  Accuracy is extremely marginal.
