I have considered having my mim jazz defretted. I bought it used a couple of years ago stock but with a gotah bridge on it. Since I have added Fender custom shop 60s pickups, new pots ,pickgaurd,control plate and shielded it.It sounds amazing ,great vintage tone. I have started to think about buying a fretless neck from warmoth intead of having mine defretted. Anyone have any comments or other neck supplier options opinions?
