Teardrop Lugs

We dedicated special attention to the re-design of the Vintage lug. Maintaining the original shape we integrated the TuneSafe system for maximum de-tuning prevention. (An update even the vintage purists will appreciate, we hope.)
Cross Laminated Tension Free (C.L.T.F.)

Drum shells need to act as solid acoustic unities as the foundation for a great drum sound. We use cross-laminated plies of beech to form a perfectly round shell with great stability. Each ply is laminated at a 90° angle to allow for a shell that is tension-free. Sonor's tension-free shells would keep their round shape even if they were cut in half from the batter to resonant side.
Optimum Shell Measurement (O.S.M.)

Our OSM shell construction (Optimum Shell Measurement) utilizes slightly undersized shell diameters to give the drum head the space to float freely, allowing unrestricted contact between the bearing edge and the drum head.
Rounded bearing edges

The rounded bearing edges deliver a warm tone with deep low end and great resonance.
