My usual set up is a Carvin b1500 through a PH412, but i like the tone of my Peavey Mark IV better. Well, i was wondering if i could some how use the Peavey to bypass the preamp on the carvin and just use the carvin as a poweramp? so i could have 2 amps used through one cab? I read i might be able to do it through the Peaveys poweramp out into the effects in of the Carvin. or is this totally wrong? Appreciate any help/suggestions.
