If you want to try something, go to a pawn shop (or goodwill) pick up a cheep guitar. The worse it is the better (if there are any good ones perhaps leave it someone else if you don't want it) modify it to your hearts content. IF you do a good job with that insterment then consider working with your good ones. If you can't do a good job on a bad insterment you will only ruin a good one.
