Hi, Looking at getting a Boss FV-500 Volume pedal, what impedance do you guys recommend.. High or Low?? I am planning to run the pedal after an Electro Harmonix Micro Pog, the POG has two outputs.. the dry (Guitar) sound and the octave sound. I am going to place the pedal after the dry output so I can reduce the guitar vol and just have the lower octave playing. The micro pog will be running through the effects send of a Boss NS-2.
