So I really don't like the feel of a 5 string but I really want to be able to have access to that B. It would also be cool to use that Gibson Grabber body that I have. Would it be possible to use the bottom 4 strings (BEAD) of a 5 string pack on a 4 string bass? or would there be an issue with scale length? I know I'd have to adjust the truss rod & intonation, but would the shorter scale length have a bad effect on the sound?
