The Warburton 9* Trumpet Mouthpiece Backbore is perfect for the orchestra player who appreciates the increased volume of sound combined with less resistance. Some sizes may require extra handling time, please contact us to confirm availability.

About The STAR Series

These were designed to allow each of the STANDARD models to be more free blowing without the necessity of reaming to a larger bore size. This is important because the quality of sound remains the same without the risk of losing focus sometimes caused by playing of too large bore size. Since these models were made available, the medium large sizes (7* to 10*) have been very well received in the orchestral trumpet community.

About The Warburton Two-Piece System

The Warburton system lets you choose a combination of rim diameter, cup style and depth, with a backbore to best balance your sound and resistance. This flexibility means you can have the most efficient mouthpiece with which to perform in any given playing situation.

The two-piece system consists of fully interchangeable "TOP" sections and "BACKBORE" sections. Due to the many demands placed upon the modern brass player, the variety of Warburton cup designs are able to produce the most desired sound in any playing idiom.

The backbore sizes compliment the cup designs and further assist in the refinement and "fine-tuning" of the sound. Consideration has been given even to the placement of the backbore into the receiver (amount of gap).

Final Cut

The Warburton system allows the player the opportunity to personally "balance" their equipment. This can now be accomplished without the necessity of traveling to a mouthpiece maker or waiting for a mail-order custom made piece that often does not work and cannot be exchanged.

Warburton backbores are available in thirteen standard sizes for Trumpet, Cornet, Schilke Piccolo Trumpet and Blackburn Piccolo Trumpet.
