I am planning on buying a five string jazz, and have a few questions: 1. I was wondering if I could string a hgh C on instead of the B, since I never need to go THAT low. The sustain will probably be bad, but will this work out well? 2. Would a five string jazz basses neck(probable an SX, maybe the fender) be only slightly larger than the P bass neck? I love playing with those thin necks, but the width seems unnatural=five strings! 3. What would be the most growling(Geddy lee style) pick-ups? I was thinking of getting some dimarzio ultra jazzes.
