Just got myself a 1975 Gibson Grabber bass. Came in pretty dirty, but cleaning it made a big difference. I suppose it is a 1975. One of the pots read 1377418. On the other pot a layer of tin makes things unreadable. The bridge cover is missing and I replaced the (Fender) knobs with knobs that come close to the original ones. Now my concern is the pickguard, it is tortoise, all other Grabbers I've seen carry black pickguards. But not all of them. In the Gibson 1975 Bass Catalogue the Grabber is pictured with a tortoise pickguard, even the Ripper carries one. There also is an add in which the Grabber features tortoise. The guard on my bass looks original. The serial number supposed to be on the oval see through transfer on the back of the headstock. It looks like Gibson put a sticker right on the serial number. It can't be removed without destroying it all, so the serial number remains hidden. Opinions please.
