1, 2, 3 - Our tightest commercial sounding backbores. These models have a concentrated and intense sound.
4, 5, 6 - Tight to medium. With progressively less resistance, these models produce a bright and very projecting tone.
KT Backbore - This backbore falls between the 5 and 6 in resistance and produces a compact sound appropriate for outdoor and Dixieland playing.
7, 8, 9 - Medium large sizes. The #7 has been our best selling model for the past nine years. This series produces a quality of sound acceptable in the orchestra as well as the concert band. Models #8 and #9 are very well received by the brass band player who appreciates the increased volume of sound with less resistance.
10, 11, 12 - Very large "Symphonic" sizes. These models have very little resistance and offer the strong player the potential for the ultimate in full, rich sound.
Styles of cornet backbores:
The STANDARD Series - Our standard series models have long established themselves as the most popular choice for nearly any playing situation.
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 may help to avoid losing focus sometimes caused by playing too large of a backbore. Since these models were made available, the medium large sizes (7* to 10*) have been very well received by orchestral cornet players.
The BC Series - These British cornet backbores are shorter than the standard cornet backbores. They were specifically designed for use with the BC tops, resulting in an overall length of 2.25". These are very popular with brass band enthusiasts.
80 Series - Most of our backbores (1 through 12 and the KT) are available with the SERIES 80 option. SERIES 80 backbores have been well received by trumpet players wishing to increase their maximum controllable volume, and by those seeking a denser, more authoritative core to their sound. SERIES 80 backbores are so named because the large "barrel" section measures 0.80" in diameter.
