Air-damper mechanics
The converter combines Roland’s air-damper system with the acoustic drum shell for its playing feel.

Independent shopping perspective
Bring a regular 22-inch acoustic bass drum into a TD-50K or TD-50KV setup with the KD-A22 converter. The retrofit replaces the drum’s head and hoop, adding a front head, sensor-equipped batter head, metal hoop, and shock-absorber cushions. Roland’s air-damper mechanics work with the acoustic shell, preserving the acoustic-kick playing feel while creating a visually substantial electronic-drum setup onstage.
