I want to take a leap into pedal modding. I read the Boss SD-1 is a good starter pedal, easier circuit and hey if I blow the whole thing up I'm only out $40. I listened to the pedal for a few days and this is what I'd like to change: 1) I'd less low end loss 2) Get a little more volume out of it. I like to crank the level and add just a little bit overdrive. 3) Too much overdrive and this pedal sounds like a chainsaw. Any suggestions? BassJunkie730's DS-1 post was very helpful because he described what each component upgrade did. Last question: What is jumping? Some mods suggest removing a component and jumping it.
