This powerhouse of a head wallops a massive 450 watts of total bass power when connected to two extension cabinets. All thats left to do now is choose your preferred choice of cabinets so you can plug in and rock! This head features two channels of tone. The Modern Channel features Bass, Treble, parametric Mid and a switchable compressor with variable level control.
