Genera? and HD? (Heavy Duty) The Genera is a 10mil 1-ply with the fat sound of a double-ply. The HD is a durable 2-ply (5mil external, 7.5mil
internal) that barks live, yet is ideal for the studio. Both models feature a 2mil overtone control ring on the underside that ?floats? with the
head, suppressing excessive overtones and controlling sustain. The ?Dry? versions feature small vent holes around the edge that eliminate
stray harmonics and tighten the sound.
