GR Trumpet Mouthpiece Backbores

GR offers 4 standard Trumpet Mouthpiece Backbores. Each backbore has been meticulously designed to provide the player with fast, clear articulations, unmatched sound, and centered intonation. Standard GR Backbores have been chosen to match particular cups in the GR line. The player may choose a different GR backbore as a custom option to match musical needs or particular horns.

T-72S Backbore

- Our tightest Commercial Backbore. High compression with a huge fat core of sound. More free blowing than conventional "commercial" backbores with a bigger sound! Ideal for large bore horns. May be purchased with optional ear plugs for saxophone players. Projects like a laser. A really big one.

#1 Backbore

- Our standard commercial backbore. More free blowing then the T-72S. Bigger sound, huge in fact! Compression with a ton of fatness in the sound. Projects a bigger core of sound than T-72.

#2 Backbore

- Our standard "all around" backbore. This plays big and brilliant - full of overtones. Ideal for all styles of playing from commercial to symphonic. Quick snappy articulations. Blow resistance seems to be closer to you down low and a bit farther away up high. Our most popular backbore!
