I'm going to say that there are a couple of major influences on my playing and I tend to bounce around stylistically between a mix of these... here is the recipe:

15% Vai, Satch
15% Yngwie
25% SRV
10% Randy Rhoads
20% Zakk Wylde
20% Me

(random Willy Wonka quote thrown in)
Willy Wonka: Invention, my dear friends, is 93% perspiration, 6% electricity, 4% evaporation, and 2% butterscotch ripple.
Mrs. Teevee: That's 105 percent!
