I'm thinking about getting a fretless SX SPB-62 (I just want the neck), but only if I can find someone to buy the body and everything that comes with it (bridge, pup, pickguard, neck plate, screws, etc.). They're $110 on the site, and replacement necks are what... $40? So, how's $60 shipped sound? I may throw in the tuning keys for an extra $10.
I think the fretless SBP-62 only comes in 3-tone sunburst, but since all I want is the neck (true, I could defret the neck already on my bass, but I don't like fret dots), I suppose you could pick, if there are other colors. Heck, at SX prices, I'd keep the whole bass, but I'm not a 3-tone sunburst kinda guy -- I like 2-tone.
