lets say, I'm almsot completely new to setting up effects, and I just got my first pedal. My AMp has an "EFX loop", which consists of 3 slots to put cords is, one says send, one says return, and one says foot switch. I'm not sure what to plug in where (say im using a single distortion pedal). I'm a n00b, I admit it. While I'm at it, I'm going to ask how you set up multiple footwitches (or are there special devices you can get with multiple buttons to press).
