I have a BSY-600 for sale. It is cool but I am using VST's and a Micron for my synth sounds. It is as new, however it does have the switch issue. If you disengage it with your heal it works every time. Just for a full disclosure. The stuff on the pad is paper-towel from me wiping it down. $35 shipped OBO. Might be interested in a cheap bass EQ, a delay, limiter, or some kind of low pass filter.
