Ok, as some of you may know, I'm looking into getting a Roscoe Beck. I'm also looking into getting a fretless four string. So I decided, hey why not just buy a fretless neck for my four string - despite my 4's cheap quality, it really does have a good sound to it. So I'm wondering: who makes a quality replacement neck (fretless, pao ferro)? I've heard good things about both Carvin and Warmoth. Anyone else I should know about? I figure that it's a cheap way to get the sound I want and to also replace the warped neck on my current bass. As always, thanks in advance for any replies.
