so, i have a couple electro harmonix pedals that i want to do a few simple mods to. just wondering if anyone has any tips or links that might help. 1-i have this ancient frequency analyzer that doesn't have an indicator light on it. sometimes you get into noisey situations, can't quite hear yourself... i would like to know what's on and what's off. any ideas on adding an LED to it? 2-on this frequency analyzer AND my big muff, i would like to add a second footswitch. one that doesn't click on and off, but turns the pedal on only when the switch is in the down position. take your foot off, and it's clean. am i explaining this well enough? i know a guy who's brilliant with this kinda stuff, but i'm strapped for cash and would rather do it myself.
