  1. what is the difference between the gk400rb-III and the gk400rb-IV, i've only had a chance to play the gk400rb-IV, and i was wondering if there was a big difference between the two heads, and wether or not the gk400rb-III is rack mountable or not, thanks

    all gk heads are rackmountable (if you get the kit). other than a newer pre-amp voicing (supposedly to make it warmer sounding), the IV has more power output than the III. :bassist:
