Hey, Sorry about the long speech here. About a year ago I bought a second hand Ibanez to learn the basics and such and I plan on upgrading/modding it so I can eventually sell it and buy a new, better one. It is completely playable but has several issues, like sketchy pots, not the best wiring and pickups that, while decent, could definitely be better. Those are easily solvable as I'm no stranger to soldering and such and it would just be a matter of taking old pieces out and putting new ones in. The most important problems, and the ones I'm concerned about, are in the neck. The tuning pegs have been replaced at least a couple times with different models, leaving ugly holes in the back of the headstock (I assume wood filler and sanding can solve those but please feel free to yell at me if I'm wrong) and the wood on the side of it is chipped, but most importantly: the scarf joint in the back of the neck separated somewhere in the past. The crack looks like this, apparently there was an attempt at repairing it before . My questions are: What can I do about this issue? Could I do it myself or should I have someone with more experience do it?
