Warburton Trumpet Backbores

The STANDARD Series
The Standard Series models by Warburton have long been recognized as one of the most popular options for nearly any playing situation. Known for their versatility and reliability, these mouthpieces are widely used by players across various musical settings.

The STAR Series
Designed as an enhancement to the Standard Series, the Star Series allows each model to be more free-blowing without the need to ream to a larger bore size. This maintains the quality and focus of sound, avoiding issues that can occur with oversized bores. The medium-large sizes (7* to 10*) in particular have gained strong acceptance among orchestral trumpet players.

The "B" Series
Internally identical to the Standard and Star Series, the "B" Series differs in its external dimensions, featuring a slightly larger outer diameter. This increase affects the mouthpiece gap, making it especially useful for trumpets with worn or improperly soldered receivers, as it helps re-establish a more functional gap distance.
