The GR 64 Series can be compared to a Bach 7 cup diameter.
With various rim contours, alpha angles, cup volumes, and backbores, the GR 64 Series has many options for players who use this popular size.
13A4a players who have issues with "bottoming out" have great success with the 64Z*, 64Z**, and 64SZ models!
Shew 1 players get better response and a fatter sound without losing the upper register with the 64ES.
