Hey guys, totally new poster here, my brother has a mexican jazz deluxe with a maple neck/rosewood fretboard. he wants to change it to a maple neck/fretboard. I've been looking online and I see that I could buy one online and replace it. Is it safe to do it myself? I already took off the old neck, and it was easy...i mean is screwing the four screws the only thing to do? or do i also need to adjust the truss rod or something? So my main question is, is it ok to do it myself or should i take it to someone. Thanks guys.
