Re: hate my inlays
as said before you can buy another prestige and swap necks. That is the option that would offer the most quality result.
You could have the neck/inlays stained darker but they are obviously the same shape.
You could spend a significant amount of money, send the neck off and have a new fretboard installed(i have seen it done but can't recommend anyone)
You could send the neck in and have the inlays redone, but that is probably very expensive as well, as it would probably require a refret. (minimum $300 usd)
The cheapest and ultimately tackiest route is cover them with stickers.
I'd just find a comparable model, and sell yours to fund that. You can always trade out pickups to emgs on the new guitar.

There are other j customs out there that have a vine. Every now and then if you look long and hard enough you can snag a decent deal on one of the 8 series.
