I have a problem getting the tone i want and i was hoping i could get some help/advices from you guys!

My gear is:

Amp: Peavey Valveking 112
Guitar: Ibanez s520EX, stock pickups
Pedals: Digitech DF-7 for distortion, Zoom 505II for delay and a Boss CS-3 for some boost now and then.

My problem with all this is that i can't simply get the tone i want, no matter what settings i try. The tone i'm after is something like this (look for the solo). So if anyone has some advices on how to achieve a similar sound, please make some noise in this thread.
