Detail 01
Free-floating external design
The damping system sits externally rather than using a glued-on damping profile.

Independent shopping perspective
For a 22-inch bass drum, Remo’s External Sub Muff’l provides external damping on heads that do not already have it. A free-floating plastic profile holds slip-resistant foam inserts outside the drumhead, so the head keeps full contact with the bearing edge. The system preserves the character of the head and shell while adding subsonic lows and increased attack, without the frequency manipulation of glued-on damping profiles. Use it in live or studio setups.
