Wow! I didn't know that. Yeah, after he tried and failed to get my Vintage noiseless pickups (brand new) working with the 4 way switch he returned the guitar to me. I plugged it in and noticed that the beautiful tone of the neck pickup had been replaced with a loud hum! I removed the pickups from the guitar and they've been sitting in a box ever since. At that point I decided to work on my own guitars.
