The two independent channels can be voiced similarly so that one channel can be used as a solo boost, or they can be voiced entirely differently by using the mid-range control in conjunction with the 3-position mid-frequency select switch. Add in separate weight controls to shape the low end response of each channel, and a global hi/low eq section that allows you to fine tune your particular amp and cab combination, and you’ve got a serious tool to create a supremely heavy sounding rig.
