You are not connecting the pedal properly. You either have to use an expression pedal, the kind with an attached TRS cable, or you have to use an "insert" cable with your FV-50L. One end of the insert cable has a TRS (stereo) plug and the other end has a pair of mono plugs. Plug the TRS end into the feedback jack and plug the mono ends into the input and output jacks on the pedal. To understand why this works, and why using a mono cable doesn't work, you must know that the feedback jack supplies a DC voltage to the ring of the plug that is plugged into it, and this voltage is scaled by the potentiometer in the pedal and then returned to the tip of the plug. You need to use a cable that will feed the signal from the ring through the pot and back to the tip. A mono cable won't do that. You can also build a cable with an assortment of adapters, but this will be less reliable. -- ______________________________________________________________ Richard Zvonar, PhD (818) 788-2202 http://www.zvonar.com http://RZCybernetics.com
