Channel 2 Crunch
Crunch is an understatement when describing Channel 2. The
three sound selections span across three generations of Marshall
with full bodied tone and the unique character which only pure
valve power can produce. The gain selections allow you to
switch from fat creamy vintage blues, to driving hard rock and
devastating metal rhythms. There is as much tonal and gain
variation in this one channel as many amps have in total.

Channel 3 Lead
The ultimate lead channel! Marshall overdrive has always set the
standard, constantly pushing back the barriers that constrain
creativity. Superbly voiced EQ maintains real tone despite
unbelievable levels of gain. By adding the gain boost and using
the selectable contour, you can focus your lead sound through
every extreme of rock guitar playing. This level of gain can't be
described in words. When you play this channel you will feel
what we mean!

with all gain controls the amount of distortion increases
as the control is advanced.
Three modes can be selected on Channel 2. Mode A is a
low gain, natural valve overdrive reminiscent of an
original JTM 45. Mode B is crunchier with the feel and
drive of a 1959 Super Lead amp or early Master Volume.
Mode C gives high gain drive similar to the JCM 900
master volume amps.
