A tip from the designer:
To help you get acquainted with the amp's fundamental sounds, I recommend that
you set all tone controls to the center or 12 o'clock position. For higher-gain, high-
volume lead sounds, your best bet is to turn the Treble knob down to prevent the
pickups and speakers from generating feedback (a setting in the 10-to -1 o'clock range
is recommended).
Each channel is equipped with a dedicated EQ so you can tweak its sound separately to
suit your taste and the given sonic scenario. Bear in mind that you also have the Sound
(1) button, as well as the two power amp Presence (14) and Depth Punch (15) knobs,
at your disposal for shaping the frequency range. Though this passive voicing section's
controls range is narrower than that of a comparable active system, its EQ curve is
tweaked specifically for its designated purpose, and will give you satisfying results.
