Am getting ready to by an ABY pedal so I can go to a 2 amp setup. Now I am a begginer and am not sure. Which would suit me better a passive or active pedal. I found 3 that I am considering. Radial Bigshot ABY which is passive. But has a lift switch an iso switch and isolation switch. Now another Radial BigShot this one is active/passive will still work without power also has lift/phase/iso switches. Then the ART Cool switch pro isolated . It's passive it also has lift/phase/iso switches. Now I maybe wrong but I read that if it is passive. You run into the possibility of being electrocuted? Is that a true fact? Or is it you have to have the grounding switch to stop that from happening?
