Not a bad price.I don't think that's a Greco at all. Looks like Gibson to me, though I'd want to check the heel shape and couple other things before I bought. There was some discussion of this bass on the FB group and I'm pretty sure it's the real deal - it's in Tacoma, not too far if anyone's serious PM me.
... but it works! I followed a hand-written letter from Seymour Duncan for correct wiring. Wish I still had that letter!
