Yamaha FC-7 Expression Pedal. I've been using it to control my Behringer BSY600---it works great for that---but with the arrival of my Source Audio Dual Expression Pedal, I no longer need it. I believe it has a 50k stereo sweep---it sounds similar to the SA DEP in that regard, and that's what the BSY600 requires. Thus this would also be a good replacement for certain Boss/Roland pedals and should match things like the Boss SYB-3 or SYB-5. Includes an integrated TRS cable. $27 shipped/Paypal. For an extra $5 I will throw in a mint Radio Shack TRS right angle adapter (a $6.50 value). Pics to come as necessary, perfect working condition, good cosmetic condition. Only trade I'm interested in at this approximate price point is a 1590A-sized dual TRS momentary footswitch (to control a Beat Buddy or Infinity Looper).
