This is an excellent mouthpiece.
The sound quality, range, sound pressure, and volume are all top-notch.
This GR mouthpiece is designed and manufactured using modern acoustics and other cutting-edge technologies.
The body is engraved with the GR logo, USA, and "Compu-Balanced 63S."
The rim was gold-plated, but is now quite thin.
The inner diameter is about a Back 12.
The outer rim diameter feels somewhere between a Back 10-1/2 and a Back 12.
The cup is shallow, about a Back E to F.
The response is excellent, producing a brilliant, speedy sound.
You can really feel the excellent pitch and consistent balance across the entire range.
The design is very efficient, capturing the vibrations of your lips inside the cup,
making it easy to control high notes.
It's perfect for everything from big band lead players to ska, horn sections, and brass bands.
It has a good resonance and produces volume even with a light blow, expanding the range of dynamics and expressiveness.
