The PJBS-350 Djem-Bass Attachment allows you to convert any Pearl 14in. djembe into a sub-sonic bass drum. To reduce the attack and add greater lows, we have included a cloth cap that stretches around the head. For smoother low-end with a slightly reduced attack, slip the included neoprene disc inside, allowing for two distinct sound options. A pedal (sold separately) attaches via an I.S.S. clamp to the djembe’s stand mounting plate. Includes two legs with mounting hardware, pedal bracket, head cover and neoprene muffler.
