I recently just won a vintage Gibson humbucker on Ebay that I plan to put in my Epiphone Ripper Reissue. The listing said it was a neck position pickup from an original Thunderbird, but I don't remember Thunderbird pup's looking like this. To me it looks like a Grabber sliding pickup, which is completely fine by me because I love the way my Grabber sounds. I just want to see if anyone here could help identify the pickup for me. If it seems like it is from a Grabber, I'd like to put it in the bridge position of my Ripper reissue since that's where I keep my Grabber sliding pup, but if it might be a Thunderbird pup, maybe I should I keep in the neck position since that's what it was originally intended for. I don't know too much about pup's, so I don't know if it would be advisable to put a neck pickup in the bridge. If anyone can help out that would be great. Attached are 2 photos of the pickup.
