I am considering a a Torpedo Captor for the studio to use with various amps. Among these amps I have a 1976 Marshall Super Lead and a 1972 Marshall Super Bass, which I would like to use. The Captor i specified to 100w, but an overdriven 70's 100w Marshall head will output slightly more. So my question is will I be able to use my two big Marshall heads at the breakup sweet spot with the Captor or will I fry it...
