Because it's a copy of a Cliff Burton of Metallica bass that had a bridge Strat pickup added for an even brighter sound (and a neck mudbucker for an even duller one).
You can see the cover for it being sprayed in post #5
Okay, well that's different! I know who Cliff Burton is (was) but I'm not a big Metallica fan.
Has anyone else ever done that, or was he the first?
