In making a guitar pick-up, do the wire that is winded around the bobbin need to be insulated? or they don't have to be?
I am trying to make a guitar pick-up. At the moment, I couldn't get my hands on a 48 gauge wire so I just used a 20 gauge wire from the dollar store and I don't think its insulated (I just want to try it out first and see if it works, its the first one I'm making anyway _ ). So my question is does the wire need to be insulated or not?
