Is the volume pedal effect the same as manipulating the guitar volume controls for controlling gain/attack? I have not tried a volume pedal yet but am recently thinking it would be good to place inline with my tuner, wah, flang, dist and delay. Also, I run the mod effects in the loop so of course if I got the pedal I would try it in the loop and out front but I am curious to how y'all are running the setup. Also considering an ISO power supply. Found a leaking battery corroding the contacts in the pack of 9v I have in storage! I would assume that this could run the pedals and amp from the same outlet with no ground issues?
