GR's "Vintage" Series Trumpet Mouthpieces. 

GR has breathed new life into sought after no longer in production vintage mouthpieces.  Original designs have been reverse engineered using the GR Design Program to remove discontinuities for a familiar feel, but with improved playing results.

61A - Al Hirt Model A

Original Jet - Tone Al Hirt Model A from the Bill Ratzenburger era.  Flat rim contour, small volume cup, GR T-72S backbore.

"As comfortable and better blowing that the "Hirt A" I played back in the 70's with better tone and a much more even and open blow than I remember on the Jet-Tone. Also, a much better core and a better low register. . BRAVO!"
