*Silver plated Medium-Large (ML) Shanks (the lower half of the backbore) are currently out of stock. We expect to have them ready to ship in June. Un-plated ML Shanks are available for shipping. Please email if you have any questions.

Wedge two part backbores consist of an upper section, which can be regular or heavy weight, and a lower shank that can be of different lengths to adjust the gap, or for improving the pitch on a C trumpet. The two part systems provided great versatility in adjusting the backbore to your specific needs.

Small - Slightly larger than Schilke A backbore. Produces a compact lead sound with good upper register support

TT- Developed for endorsing artist Terry Townson. Intermediate in characteristics between Small and Medium backbore.

Medium - Similar to Warburton 7 or GR #2 backbore.

Medium-Large - Similar to Bach 10 backbore. This is an excellent all round backbore suitable for orchestral playing.

Engstrom ML-L - This is the signature backbore developed for Howard Engstrom of the Calgary Symphony Orchestra. It is intermediate between the ML and L backbore.

Large - This is our largest backbore, similar to a Bach 24. This produces a broad orchestral sound when paired with the appropriate top.

    Back Bore Change

    Posted by Richard H. on 2019 Apr 10th

    I have been searching for a way to improve my range and endurance. I finally decided that the Large Bore I was playing was just to big. I decided to move to the medium bore. I have not been disappointed. I have a more focused sound. I have improved range and endurance.
