Q-mass DUO: Sound improvement for Saxophones

Please note: This is a set of two Q-mass screws, both fitting on your tenon from each side of your instrument. Please order the Q-mass SINGLE if you only want one Q-mass.

As sound travels through solid objects, it’s causing it to resonate. Yes, sound does travel trhough solid objects. Your saxophone body contributes to the sound, believe it or not. In fact, sound travels about 14x faster though brass than through air.

While the concept of the Q-mass may not be new, it is an innovation in the sense that it passes along the vibrations that originate in the neck, to the body by adding weight to the screw that holds the tenon into the body. The existing link between body and tenon is far from ideal in most cases; in fact any connection may impair the transmission of vibrations that contribute to sound. If this is a weak spot, your sound will be affected in a negative way. The oscillating air column in the instrument body may be impaired, too (we haven’t be able to prove this, though). The connection between neck and body is enhanced by the Q-mass and aims to eliminate these negative effects. You could also apply the Q-mass on the body-to-bow section (contact us as we can provide you with the best solutions based on your brand). Sure, we also had doubts about adding weight to a screw on a ring that embraces the tenon of the saxophone neck. However, after a year of testing and development we’ve decided to bring the Q-mass to market, making it available for saxophone and trumpet. Musicians that have tested the Q-mass are thrilled and have made it part of their go-to setup. The Q-mass may appear to be simple, but can make a world of difference once in place! Allard Buwalda, Jan Menu and many others are convinced. The Q-mass replaces the standard screw. Made to order for almost all brands.

Please try before judging.

Socratic.org: We hear the sounds emitted from solid objects because of resonance. Resonance is when an object oscillates at a specific frequency that causes it to increase in amplitude. This is simply moving back and forth, like a heavy metal guitar string! The string oscillates back and forth at its resonant frequency, and pushes against molecules of air, which causes the air to push against other air molecules, creating a sound wave since the air is less dense. The wave travels all the way to your ears, for you to enjoy.
