I don't know if it would be more appropriate to put this in the Luthier's Corner or in Hardware, but hopefully I'll get enough advice here. I really like the idea of a six string, though the sheer size of many six string necks has always turned me off to them. For me, the neck is the single-most important feature of any bass I play. I was looking at a fairly-beat up American Deluxe Jazz five-string with a cracked headstock near the B string tuner, and since I was planning to replace the neck anyway, would it be possible to convert this to accommodate six strings? Here's the ad: http://losangeles.craigslist.org/sfv/msg/1985559437.html I consider that crack to be a pretty major structural flaw, and I was hoping to put a fretless neck on anyway. The body, to me, is pretty beat up as well, so I've shot him an offer for $400 so far. Would my time and money be better spent converting another bass, or will this do just fine?
