I have a cheap (Johnson...) J bass that I would like to convert to a playable fretless. I put EMGs in just to be able to use it, and the 'burst finish and white pickgaurd are actually decent. I would like to put a new fretless neck on this bass, and I actually prefer the P bass nut-width - any recommendations? (I have looked at the Warmoth site, and could use them, but they are not cheap.)
