The Full Force FB single-ply medium-weight bass drum head features an acoustically vented damper ring hidden in the hoop on the underside of the head. The damper ring helps control overtones and features vents along the perimeter that allow the ring and head to move as one.

This clear 10-mil head has a powerful attack with exceptional projection and just the right amount of tone control. It works well when you need an open, powerful-sounding bass drum without unruly high-frequency overtones.
