Dear Marty Friedman, I'm saving money for a big amp, I would to like to know your opinion about the channels of the blue voodoo by crate, because unfortunatly I never have the opportunity to test one, and I don't know nobody that have tried it too. I like the marshall sound, but I think marshall's don't have a lot of low frequency. I played metal stuff like megadeth, metallica and pantera. thanx a lot! Gustavo
