Hi there, I have a mexican tele that has been great, but I recently had a set of vintage noiseless pickups installed. When I got it home and plugged it into the same amp w/ the same chord and I got a terrible buzz that goes away completely when I I touched the metal on the pickup selector. As soon as I take my finger off the metal it starts to buzz again. Does that sound like the pickups weren't installed well? Please let me know if you have any ideas.
