Warburton H Backbore Modular Trumpet Mouthpiece Part

This is a modular Warburton H Trumpet Mouthpiece Backbore. This part is ideal for commercial / lead playing, and is well suited to the high register of the trumpet. In good condition with a moderate amount of cosmetic scratching. Some minor nicks are present. No effect on playability. Round shank.

From Warburton: “The​ ​‘H’ backbore fits squarely into the commercial category ​as it seems to perform best with a fast moving airstream associated with shallow cups. Featuring ​a longer blank with reverse taper in the venturi, the ​‘H’ is preferred by strong lead players who are able to convert the high resistance into an efficient and focused buzz. The benefit is that the ‘H’ projects the full spectrum of their sound rather than just making the highs more piercing.​“
