I recently purchased an early 94 Les Paul R7. It came with the original pickups but the bridgr pickup had been taken out and put in the case and replaced with this pickup. Does anybody know what this pickup is? It says Gibson USA and it looks like in pink to the left is a 13.
That 13 might be the reading on a meter. If so, that’s one of them hot ceramic pups like a 500t. Can you check the resistance and post pics of the top without the cover?
