Sound:
Any guitar with a tremolo system that doesn't have a locking nut on it *will* go out of tune horribly. That is a fact. The strings will move in and out of the nut as you push and pull on the tremolo bar, get hung up in tension, and change length, therefore affecting tuning stability. Every other Kahler-equipped guitar brand (as well as Floyd Rose) that I have seen comes with a locking nut. Kahlers are DESIGNED to have a locking nut. This is a serious and unforgivable blunder on Gibson's part, and this is not the first time they've done this. It makes you wonder if the people designing the guitars even know anything about them (or at the very least, anything about tremolo systems). If you buy one of these, and actually want it to stay in tune, you'll be going to Kahler's website and buying an aftermarket locking nut. And for a guitar this expensive, that is unnacceptable.

Sound:
Way overpriced! Slap a couple EMG's and a Kahler bridge on it, so it's worth a couple thousand? I DON'T THINK SO, GIBSON!!!
