guys, I'm looking for a distortion pedal. Now, the tone I'm looking for is like the one Blacky of Voivod used to get. I emailed him and he explained what he used. It was basically a Marshall 900 guitar head that was cranked max and had 2 out of the 4 tubes removed so they would be overloaded. Is there any pedal that can do that? maybe one of those electro-harmonix (ehx) muffs? Thank you.
