I play music in a room that does not have any heavy duty electronic stuff going on...no fluorescent lights, hungry computers, electric heaters, etc. Why I have an issue with just about any active pedal (OD, Comp, Wah) is a bit of a mystery. Example: recently I bought a wah. It was totally noisy in the toe-down position, which was a drag, as I really wanted THAT one brand of pedal. Had to take it back. How might I solve this issue and have a quiet board? Do I need a noise gate, a power source...how can I solve this recurring issue?
