So I just bought a cheapo p-bass which I need to change the neck. I really don't want to pay very much for the new neck and I want lefty maple neck with blocks. I really only found one and it has 21 frets and the previous neck had 20. That's what I call sticky situation... The necks both are 34" scale. So how can I fix this situation. Can I just move the saddles, bridge or cut piece out of neck or move or what?!
