Quick
Comparison - The GR 3 Series cup diameter is similar to a conventional
3 diameter. The 3M is a very popular choice for 3C players looking for a
familiar feel but with more core in their sound and more improved articulations. All 3 Series GR Mouthpieces have the same rim
and alpha angle. This provides a consistent feel between all GR 3 Series Models,
allowing the feel to be the same to easily meet any musical demand. Classic Blank is standard. Symphonic Blank is standard on the HC** model. Studio, Symphonic, and FatBoy are available as a special order on some models. Backbores, other than listed, are special orders. |
