7. Deep Switch- Boosts the low and low-mid frequencies. This is a low fre-
quency contour switch, changing the low and low-mid response.
8. Reverb Send- the reverb drive control determines the amount of signal
applied to the reverb tank. Low settings will create a very open, small
room reverb effect with a short decay time. Advancing the control clock-
wise increases the signal applied to the driver, and a very saturated effect
with a sharp attack and a long decay can be obtained.
9. Reverb Return- the reverb return control mixes the reverb effect signal
with the dry signal. At full counterclockwise rotation, the reverb effect is
defeated. Using the return control in conjunction with the reverb drive
control, a wide range of natural reverb effects can be produced.
10. Contour Control- The contour control is an active wide band sweep. In the
12 o’clock position, the amp’s frequency response is flat. Counterclock-
wise rotation reduces high end response and increases low frequencies.
Counterclockwise rotation decreases low end and increases the high fre-
quency response. This control is very useful for maintaining preamp tone
control settings, while allowing a global adjustment to compensate for dif-
ferences 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.
11. Input Gain- Adjusts the overall gain of the amplifier. Start with this control
in the 12 o’clock position.
12. Master- Adjusts the output level.
13. 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.
14. 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.
