So I'm a little confused about the whole ground loop thing in reference to guitar circuits. With this in mind, I have a few questions: 1) Can ground loops theoretically form in the first place in a normal guitar guitar circuit (e.g. a telecaster circuit) 2) Assuming they can form, what wiring configuration sets this situation of potential ground loop problems. 3) With #2 in mind, how can I avoid ground loops in my own tele circuit. Are there any rules of thumb? Thanks for the info!
