Hello all, my first post to this forum, although I've been a lurker for a while. About 13 years ago, my Dad bought a Rickenbacker style bass from a friend of mine for £15. It was missing the bridge pickup, but was mostly intact. The guy it belonged to had drawn all over it with green marker pen and had scratched something all along the fretboard for some reason! Anyway, as my Dad had just built me my first bass guitar, he took it upon himself to try and restore it. This being pre-internet days, it was pretty difficult to find out about the bass other than it seemed that the price of the replacement pickup would be fairly high and I think he just lost interest. He managed to get rid of the marker and most of the damage to the fretboard, as well as re-lacquering the body and neck. Since my Dad died 5 years ago, the body's been sitting in a wardrobe and the rest of the bits in the garage. I've decided I'd quite like to have a go at putting it back together and turning it into a working bass again. I have no idea what it is, but it looks like a fairly good copy to me, although I have only seen real 4001s in photos and never played one. It doesn't look like the pictures I've seen of the more famous 70s law-suit copies like Ibanez and Univox. Anyone have a clue as to what this bass actually is? I've posted some photos below. The lacquer that my Dad used seems to have cracked. The only marking we could find originally were three letters - NAT (for natural I suppose) - marked in the well where the pots go. This can't be seen now due to the work my Dad did. It is stereo, which I gather is something not all copies were in the 70s. It also has a thru-neck and triangular inlays on the fretboard. Another aspect worth pointing out is the dual truss rods. So all in all it looks, to me, like a pretty faithful rendition of the real thing. I'm certainly no expert in guitar restoration, in fact I'm a complete beginner, but it looks like it wouldn't be too difficult to get up and running. Can anyone suggest a decent replacement pickup for the bridge that wouldn't cost too much? I'm pretty sure most of the other parts are present, so it should just be a case of putting it together. Any help, suggestions, ideas what it could be would be most appreciated. Here are the photos - http://www.flickr.com/photos/fractalpotato/ Sorry if this is in the wrong forum.
