I know Peavey Valvekings aren't the greatest for distorted tone...

But I own a peavey valveking head and cab, and am looking for a way to mainpulate the tone.  When i recorded this http://www.battleofthebands.com/lonelycitydropoff i ran through an orange head and a marshall cab.  But i can't afford an orange head.  Any ways of manipulating that tone?

Pedals and wireless systems will, but they suck tone, not add to it.

Save for an orange head if it means that much to you.
