I'd like to get more depth from my 1980s Fender Jazz Bass Special and purchasing another with more strings is out of the question at the moment. It seems like it would be pretty easy to outfit a 4-string for use with the lowest four strings from a 5-string set (B, E, A, and D). I imagine I'd just have to get someone to cut a new nut, right? Is there anything else I should know? Does anyone here play this way?
