If you don't mind me asking, Rob, what is the wire that is running from under the lower pickguard to what looks like the input jack? It looks like it was supposed to go to the light circuit control pot, but I don't see the pot and don't recall ever seeing the wiring come out from "hiding" like that anyways.
"Here he is, come to pay homage to the Rickenbacker display!" (Said to me by owner Bruce at the "Great House of Guitars" in Rochester, NY)
Don't feel daft at all, Rob! If you actually had one, I'd be booking a flight now just to 'ave a gander'!!
I think there are 2 or 3 forumites who own one, but I suspect there are more than a few hidden away in locked cupboards or bank vaults around the world!
In addition to not having the original pickups, the MG 331 pictured in this thread doen't have the original light circuit. With the lights on, you can see there are 'too many' lights (thats my take anyway, it could be the way it was photo'd), and most likely that wire going in the body is providing the power - it doesn't look the the original power jack is being used at all. With the lights out you can see that the 'light boards' are gone - the original boards are a light cream/white color and you can see how dark it is in the body. I have no real information on the guitar, but my gut says it 'lights up', but really no longer has a circuit to provide a 'lightshow'... too bad. Anyone know more about it?
