(i have a fender starcaster strat) The other day i broke apart a crappy pickup and stuck its bar magnet to the bar magnet of the neck pickup, now it gets a very good acoustic tone with the pickup's tone knob up all the way (and the volume doubles compared to the mid/bridge pickup), but my question is this, does adding another bar magnet put my guitar at risk for some sort of electrical mishap or wire/sound problems along the way?
I'm sure there you'll lose sustain and have a dampened attack but I wouldn't really know.
It's not going to blow up your guitar, though.
