What are the characteristics of the Q Backbore? Print

Highly efficient - The player's buzz is amplified to a vibrant sound, even in the mid and low registers. This makes it possible for lead players to remain authoritative in these registers without having to overly-loosen their chops. This pays off big in the endurance department.

Resistance - similar to our #4 backbore, but the increased quantity of sound requires less physical drive to sustain dominance. An entirely new reamer was created to make the Q backbore so more specific comparisons aren't possible.

Slightly lower pitch center - The Q is .050" longer in length overall than our standard backbores. This added a unique type of resistance resulting in firmer "walls" around the slots. If you are playing at extreme volumes, this type of security can make the difference between a guarded performance and a boldly dynamic one. Most players who use the Q have found that their tuning slides can come in as much as a quarter inch, resulting in a more consistent timbre and better intonation.

Commercial sound - Make no mistake here - the Q was designed for verve and projection.

Why the funny name? - Actually the designation "Q" was used during its development as a working name because the letter Q was not used in any other product that we make. Later, we learned that the "Q" factor is used by pollsters to describe someone's immediate likeability. If someone has a high Q factor, most people like them upon their first encounter. Serendipitously, this is precisely what happened with this backbore, so we kept the name!


"I have used the KT backbore since 1987 with good results and therefore had no intentions of looking elsewhere until I tried one of the new Warburton Q Backbores. The Q really opened up my extreme upper register and seems to slot better in that register as well. The sound has even more cut but maintains a good core at the same time." Steve Hawk
