I have a Gibson SGJ where the stock pickups have the 5-pin connectors that plug into a pre-wired board. I just got a Railhammer Anvil pickup that I'm looking to drop into it but am not sure how. Do I just cut the wires on the 5-pin connector and solder the connector to the pickup wires?
Yeah, you can do that. Or spend a few more bucks and replace the pots and other wiring too. Then you don't need to worry about the connector.
Honestly if I were you I would just replace everything. I have the solder less
thing on my les Paul and if I ever swap pups that's what I'll do. I just haven't yet because I rarely play that guitar.
