personally for a guitar to shred on, I prefer the parker fly. my uncle has one and whenever we jam, he likes to play his semi-hallow epiphone, so I get to play the fly. it has amazing tone, and the tremolo is by far the best I've every played

if you're on a little more of a budget, I would recommend an ibanez.

and I would have to agree with superhuman about not getting a different shaped guitar if you're just starting out. my first guitar was an x-shaped carvin, and I still play a little weird because of how it sits. now days I only play it when I'm out because of the compliments I get on it.
