So I swapped my bridge pickup today. Initially when I put it in everything was fine, other than the tinny sound I was getting from the pickups because I mixed up the hot and ground wires for the bridge pickup. No deal..opened it back up and switched the wires. Plug it in after the fact and its humming and crAckling badly, and its hard to say whether or not the pickup is performing at its full strength. If I hold down the volume knob it stops the hum. I opened it back up ans resoldered the two connections, made sure everything was tinned..but when I plugged it back in..same deal. Now..I noticed my soldering iron wasnt generating enough heat to melt the joints to the pot casing, I had a good deal of trouble with it. So I'm guessing its bad solder joints causing this? The new bridge has a little wire soldered to the baseplate, which acts as the ground..right? So I'm all set there.
