Hi there guys, I just received my 74-75' ish Gibson Ripper guitar that I just bought off eBay about two weeks ago. I know I should take it apart to find out more about it but I figured that some of you guys here know a lot about vintage gear, so why not take a shot. Right off the bat, I've got some interrogations about the bridge pickup. It's definitely been added at a later date, not an original. On the back of the headstock there's a Dimarzio sticker with another smaller one underneath reading 79876-1. I guess that could be an identification helper for the pickup model. I'm figuring, why would you put a Dimarzio sticker on a bass if the added pup is not a Dimarzio, right? So, the only thing that the number returned on a search on the internet was for a past auction off eBay for 70's Dimarzio Distortion Humbuckers for guitars. Could that be it? I mean the bass version of that pickup? I've never seen a cream white humbucker like this one. Any ideas? Also, about the control switch. All of the Rippers I've seen online always had a dial switch. Did they make that kind of switch on 74-75' Rippers or was it added at a later date? I know the knobs aren't original, I'll try to find black ones sometimes in the future. Anyways, I can't wait to try this one in my jam room tomorrow night. A 15 watts amp with headphones in my small apartment just won't do it justice.
