I think what your lookin for is an Ibanez tubescreamer, but if you have the money ($160) You could have alot better pedal check out robert keeley's mod to the pedal if you care alot about your tone check out
www.robertkeeley.com and look for the ts-9 mod plus and read how drastically his mod enhances the pedal. If not the tubescreamer get a bluesdriver and once again check out robert's mod to the bluesdriver.
I am Comfortably Numb... :D
Oh yeah...STICK IT TO THE MAN!
