Purchased a EC Strat last month. love everything about it, except it is battery powered. If I ever decide to change PUs can this be done without mods to the guitar? As I understand it, adding EC PUs to a standard Strat requires mods to the body. Second question, whats a good source for a replacement back plate, I would like to get something different. Thanks I had also purchased an American Standard Tele to compare against the Strat. The Tele is going back. I just could not get to like it anywhere near as much.
