Kanstul Modular Trumpet Mouthpiece Backbore - Reeves 69

Description

Genuine Kanstul modular backbore, used for a few years.
Good for big band playing, the 69 backbore records well with a bright, focused sound. This is very popular on our shallower cups. Good if you like to power the upper register. So named because Bob Reeves developed it in 1969. Threaded to match Kanstul and Warburton modular cups! This backbore is no longer available.
Kanstul Musical Instruments was the pioneer in single-point scanning and accurate mouthpiece design and reproduction, and at one time offered more than 300 models of professional mouthpieces.
Selling from my private collection. This backbore is unmodified, threads are clean. I probably already blew all the bad notes out, so this is good to go!! Shipped with USPS First Class. International shipping available on request.
