*Please note this is a shell pack only and Hardware and Cymbals are not included.* Birch - the secret behind acoustic versatility SQ1 drum shells are made of 100% European Birch. Because of its sound characteristics - balanced in low, mid and high - the Birch drum sound is very popular for studio recordings as well as live performances. When developing SQ1, Sonor tested several combinations of Birch-based shell materials. Sonor''s conclusion was that pure Birch provided the most versatile sounding drum. Sonor''s unique CLTF Cross Lamination Tension Free and OSM Optimum Shell Measurement process (slightly narrowed outside shell measurement) provide excellent sustain and easy tuning. Sound Sustainer - the intelligent drum mount For decades Sonor has cooperated with scientific institutes to optimize the acoustic performance of their drums. Numerous pioneering concepts for the improvement of drum mounting systems have been developed. The new Sound Sustainer technology is based on concepts applied in the automotive industry. A 2-component connection (rubber to metal) enables complete isolation of the metal mount and the wooden shell. This guarantees a particularly long lasting and clean decaying sustain, not just for tom toms but also all floor toms in the SQ1 series. SQ1 Look & Feel - inspired by classic cars The colors and styles of legendary car classics were the inspiration for the color selection of the SQ1 series. Four matte lacquer surfaces are handcrafted with Sonor''s precision sanding, polishing and lacquer procedures. A special lacquer is used to seal all inside shells.
