I have just started reaching the tone that I would like to have. I play through a Fender 2x12 Hot Rod DeVille. The problem is that when I click on the dirty channel on my amp it basically sounds like crap. I like to build up the intensity in my music and when I hit that channel it throws me off. Is there a way to have a rack E.Q. just for my dirty channel? Maybe with a foot switch to turn the E.Q. on and off? Anyone HELP. Thanks
