Played a Gig this past weekend with my Gnarly JCM 800 2203 into a 2x12 Bogner Cab. Had the Amp Cranked. Hardly none in the PA. Of coarse we were outside at a large event (for me). Man did I have the tone going on. I cranked the amp and used a pedal to cut the volume for lowere volume dirty rythem. Used my guitar volume for cleans.
