Front Panel
1 Input
¼" unbalanced input jack. Plug your guitar in here using a shielded cord.
A tip from the designer:
Depending on the type of cord and its shielding, you may occasionally encounter interference from
sources such as radio stations or powerful magnetic fields. When this occurs, try connecting your guitar
to the amp using different cords. What's more, to minimize signal degradation due to high-frequency
loss, use the shortest cords feasible (as a rule, the shorter the cord, the less susceptible it is to
high-frequency attenuation).
2 Clean Gain
This knob determines input sensitivity of the Clean Channel, in other words, the input level
of the preamp during Clean mode.
A tip from the designer:
The amount of distortion depends on the type of pickups your guitar is equipped with. Single coil
pickups may overdrive the preamp when the knob is set to about the two o'clock position in Clean
operating mode, pickups with very high output levels (humbuckers or active pickups) will evoke
distortion at even lower settings. If you want squeaky clean tone, simply back off the Gain knob
accordingly.
3 Lead Gain
Gain control for the Lead Channel. This Control knob determines input sensitivity when the Lead
channel is active. Use it to dial in the desired amount of preamp saturation level.
CAUTION:
Extremely high gain and volume levels in Channlel 2 mode can produce powerful feedback.
Avoid feedback squeals; they can lead to hearing loss and damage speakers! At higher volumes, back
off the Gain and Treble levels in order to prevent unchecked feedback!
4 Bright
This feature boosts the upper end of the high frequency range for the Clean channel. Its intensity
decreases as gain settings increase.
A tip from the designer:
For a crisp or glassy tone, activate the Bright boost. It brightens the sound of humbucking or muddy
pickups. Use it to tweak the amp's tone to taste, activating it to boost top-end frequencies for the
Clean channel or deactivating it to dampen high end response
.
