AMP switch and selector, LED
Here you can select the amp mode.
Each time you press the AMP switch, the bank and
AMP LED color will change as follows:
• STD (Standard): green
• SPL (Special): orange
• CST (Custom): red
• EXT (Extra): blue
Use the AMP selector to choose a model within the selected amp bank.
The operation of the gain circuit, and the response of the tone controls and
their location within the circuit are all switched according to the amp model
that you select here.
In Preset mode (i.e., when the PRESET LED is lit-up), you can recall preset
programs that contain sounds and effect settings that are typical of each amp
model.
GAIN control
This adjusts the pre-amp gain of the selected amp model.
VOLUME control
This adjusts the volume of the selected amp model.
TREBLE, MIDDLE, BASS controls
These adjust the tone for the high, mid, and low-frequency ranges. The
changes that are produced by each control will differ depending on the amp
model that you’ve selected.
MASTER volume
This adjusts the volume that is output from the pre-amp to the Valve Reactor
power amp. This setting will change the amount of the Valve Reactor’s distor-
tion.
NOTE: The MASTER volume setting is not programmed.
NOTE: The amount of Valve Reactor distortion is also affected by the
GAIN control and VOLUME control. With some settings, there will be
almost no distortion.
