ProZone Insight

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.
