Used Roland KD-8 Kick Trigger Pad

From Roland:

Drummers will appreciate the V-Tour Series TD-6S’ new upright kick drum trigger. The new KD-8 Kick Trigger Pad’s vertical design not only gives drummers a better feel compared to reverse-type kick triggers, but it also reduces trembling so you get nothing but solid kick sounds. And here’s more good news… the KD-8 can even accommodate double bass!
