I've a 1974 Ibanez rickenbacker 4001 copy and I can tell you it's a great damn bass. But the truss road is broken , and the relief is a kinda of gran canyon now. The fact is the neck is not body trough but bolt on , so I wanna swap the neck like people do on jazz or precision. But where I can find one exactly at mine? I suppose I've to go to a luthier in town isn't?
