Its a pretty nice guitar. It depends which one you mean ! My friend has a zakk wylde signature guitar fitted with emg's and it sounded really good even when played through a small 15watt fender amp. Its quite heavy but i guess its ok if your just going to sit down with it.
I know there is the camoflaged signature one as well which costs even more.
I think they are pretty cool guitars.
Best thing to do it to try and test one your self !
By virtue of their electrical properties, tubes generate a special waveform when they're saturated, which is why tube engineering has tremendous tonal advantages over solid state or DSP solutions, particularly for crunch and lead sounds. Tubes enter the saturation zone gradually or softly, which lends tube-driven tone its trademark yet totally unique character.
