http://tinyurl.com/muxwk Pic taken from directly above a standard VOX bass. AFAIK this has never been modified and you can see the cuttout shape in the body for the pickups. Just looking at this though, the string alignment above the pickup heads doesn't seem to follow any pattern (I mean distance from centre of pickup head to string X. Does this matter much? Where would the idea alignment be? I'm guessing each string should go midway between a pair of heads. As I'm writing this I'm wondering if it is the bridge that's "wrong" here. If it went down (in the picture) slightly the strings *would* be midway. I don't know if there's an adjustment on the bridge to do that.
