Lead Gain
- Adjusts the input level (gain) of the lead channel.
Lead Master
- Adjusts the output level of the lead channel.
Lead Channel Switch
- Sends the instrument signal through the lead circuit, adding extra stages of gain
to the signal and enabling the lead gain and lead master controls. To enable foot switch control of this
function, switch must be in the down position.
Bypass Switch
- This switch bypasses the tone controls, increasing both level and mid-range response.
To enable footwitch control of this function, switch must be in the down position.
Reverb
- The front panel reverb control is the return, or mix, control. The reverb effect is defeated with
this control in the full counter clockwise position. Use in conjunction with the reverb drive control (see
REAR PANEL FUNCTIONS, next page).
Contour Control
- The contour control is an active wide band sweep. In the 12 o’clock position, the
amps’ frequency response is flat. Counterclockwise rotation reduces high end response and increases low
frequencies. Counterclockwise rotation decreases low end and increases the high frequency response.
This control is very useful for maintaining preamp tone control settings, while allowing a global adjust-
ment to compensate for differences in room acoustics, speaker cabinets, or bright to dark guitars (PRS
Humbucker to Strat, for example). This control also actively reduces the articulation available, allowing
a softer setting, or extremely open and revealing, depending on your individual style and requirements.
Stand-by Switch
- Should be in the “down” or “stand-by” position when you apply power to the unit.
After a few seconds, place the switch in the “up” position to use the amplifier. You may leave the unit
“powered up” and place this switch in the “stand-by” position to mute the output.
Indicator Lamp
- This lamp will illuminate when the power switch is in the “up” position, indicating the
unit is receiving A/C power.
NOTE: All switches are ON in the “up” position
