okay, i have a Fender Standard Jazz Bass of the five string variety. In case this detail become important, the adjustment for the trus rod is at the headstalk. I want to get a new neck for it, a fretless one. I went to warmoth and saw that they had fretless necks that look most excellent, however, i'm not sure if they would fit mine. Not only is mine a standard as opposed to a delux, but also my current neck has only 20 frets while theirs have 22. I'm all for more frets (or less frets considering this would be a fretless neck, you know what i mean), but wouldn't this create some sort of problem? I'm all for any modifications to my bass to make this work, but if anyone seems to know more about this than I do, leave me some feedback or email me at firstname.lastname@example.org thanks in advance for all the help that I know you fine people will give me.
