independent channel has its own Drive and Level controls,
which allows you to set them relative to each other. The
Master Output Section's Volume control can then be set for
the particular occasion - songwriting at sunrise or grinding

each channel can be turned off, you can designate how many
you want to switch between: all 3, 2, just 1, or even none.
Turning off all 3 channels enables you to use the Speaker
Simulator and Master Output Section only. This feature is
useful when you want to record direct using any other pre-amp,
fuzz box, or effect unit in your collection.
channel switching with a single footswitch is another Tech
21 innovation. The custom footswitch actuator provides a
smooth transition between channels for instantaneous switching.
Though deceiving in design, you're never more than two stomps
away from the sound you want.
