Here is a detail of the gibson 50s wiring:
The tone pot changes have been discussed as not necessary unless you want the full vintage vibe. It can't hurt, anyway.
The key to this is the moving of the tone pot connection from the pickup to the switch. The typical quote of "just move the cap wire from the outside lug to the inside lug" is not accurate. The truth of this of this mod is moving the cap wire from the pickup wire to the switch wire. This is an important distinction as some users have their pickup and switch wires reversed so as to attain independent volume controls (turning one pup to zero when in middle pos only kills that pup instead of killing both).
