FRONT PANEL FUNCTIONS
[1] INPUT: Input for all types of instruments, e.g. guitars
with single-coil, humbucker or active pickups.
[2] CHANNELS: Selects the Clean or the Overdrive
channel if no external footpedal (e.g. the FS5-G) is
connected to the FOOTPEDAL jack ([BP 4].
[3] DRIVE: Adjusts the amount of gain in the Clean
channel.
A totally clean sound is achieved at lower settings (1-4). At
middle settings (4-7) the sound will get more juicy. At high
settings (7-10) medium overdrive occurs which will produce
more sustain and a subtle distortion.
In order to maintain the volume at the same level the
Volume knob [4] has to be turned down.
NOTE: The best setting also depends on the output level
of your pick-ups. For example to get a clean sound 1-3 will
work well for high-output humbucker pick-ups while 2-4 the
best range is for low output single coils.
[4] VOLUME: Adjusts the volume level of the Clean
channel.
[5] BASS, MID & TREBLE: Classic passive tone controls
for the Clean channel.
[6] GAIN BOOST: Selects Medium Gain for Crunchy
sounds (down) or High Gain for Lead sounds (up), in the
Overdrive channel.
[7] GAIN: Adjusts the amount of distortion in the Overdrive
channel. A cleaner sound is achieved at lower settings (1-
3). At middle settings (3-6) the sound will get more
distorted and harmonically richer. At high settings (6-10)
high-gain overdrive occurs with more sustain and
distortion.
NOTE: If the Gain Boost is switched on, squealing
and/or excessive hum and noise may occur at high
Gain settings, due to microphonic guitar pick-ups and
insufficient screening of guitar-circuitry.

WARNING:
* TO REDUCE THE RISKS OF ELECTRICAL
SHOCK, DO NOT REMOVE THE COVER.
* TO REDUCE THE RISK OF FIRE OR SHOCK
HAZARD, DO NOT EXPOSE AMPLIFIER TO
RAIN OR MOISTURE.
* THIS APPARATUS MUST BE EARTHED.
* TUBES ARE HOT.
DO NOT TOUCH DURING OPERATION.
[8] VOLUME: Adjusts the volume level of the Overdrive
channel.
[9] BASS, MID & TREBLE: Classic post-distortion passive
tone controls for the Overdrive channel.
[10] PILOT LAMP: Illuminates when the Power is switched
on [BP 1].
[11] STANDBY SWITCH: Allows THE GREG to be placed
in Standby (down) or Active (up) mode. In Standby mode
the tubes remain hot, but the amplifier is not operational.
TOP PANEL FUNCTIONS
[1] ON/OFF: This switch places the OTS circuit in the
signal path if no external footpedal (e.g. the FS5-G) is
connected to the FOOTPEDAL jack [BP 4].
[2] DRIVE: Adjusts the amount of (output tube) distortion of
the OTS circuit.
[3] VOLUME: Adjusts the volume level of the OTS circuit.
NOTE: OTS stands for Output Tube Saturation. THE
GREG is equipped with a 0.5 Watt all-tube power amp, not
for driving any speakers but pure for creating new
harmonic structures. This unique feature enables you to
add real tube-power-amp distortion to all your sounds,
clean as well as distorted! If The Clean channel is on, you
can create nice and musical saturation of clean tones; in
the Overdrive channel you can really fatten up all your
crunchy or even your high-gain distortion tones.
If the OTS is activated, the small tube-power-amp is placed
in the signal path, like it was plugged in as an effects unit
in an effects loop.
[4] MODE SWITCH: Selects between Harmonic Vibrato
and Tremolo effect. The Tremolo effect varies the volume
of the guitar signal. The Harmonic Vibrato effect varies
both the volume and the phase of the guitar signal.
