properly screened “guitar” cable for interconnection. There
are many different makes of guitar cable available, ranging
from fairly inexpensive to very expensive. Each have
different characteristics, and depending on your particular
guitar will give different results, all very confusing for
the inexperienced! For instance, a “cheap” cable with
high capacitance (which would normally be termed as a

frequencies. Alternatively, a very low capacitance cable
can help brighten up a muddy sounding hum-bucker type

and your guitar best. Hopefully your dealer can help you
choose the right cable. If using an FX pedal system then
the best advice is to use a high quality, low noise, and low
capacitance cable from pedal to amp.
GAIN (normal)
– This controls the level of the Normal
channel. At lower settings the sound will be clean and will
have a bit of treble lift that will compensate the sound to
enable your ear to hear a good spectrum of tone without
it sounding flat. At higher control settings the sound will
thicken up and get louder. As it reaches maximum volume
the sound will “crunch” up as the amplifier circuit will
start to be overdriven. A word of note! Different types of
guitars and pick-ups have very different tonal characters
and the voltage level from the pick-ups can vary by quite
a large amount, thus the control positioning will vary
depending on your guitar and what sound you want. As

and a brighter sound. Guitars with Hum-buckers will have
a thicker louder sound. Also pick-up height has a great
influence on tone and volume. Further away from the
strings will be cleaner and quieter, closer to the strings will
be fatter and louder.
VOLUME (normal)
– This quite simply controls the
output of the sound generated by the normal preamp,
giving you the required sound level and balance that you
require.

GAIN (overdrive)
– This control determines the amount
of signal that the preamp circuit has to produce the
overdrive sound. Low settings will produce an almost
clean slightly crunchy tone, whilst higher to maximum
settings will produce intense overdriven distortion tones.
VOLUME (overdrive)
– This quite simply controls the
output of the sound generated by the overdrive preamp,
giving you the required sound level and balance that you
require.
TREBLE, MIDDLE, BASS EQ
– The EQ circuit
works on both the Normal and Overdrive channels. The
AG40DFX EQ system is of the time-honoured passive
guitar amp system as used by virtually all guitar amps
even the very greatest pro amps, but with an added bass
boost circuit that gives the AG range of amps added
warmth especially at low volumes. This type of tone
shaping is very wide ranging and very versatile, although
please remember it is also very interactive so that each
control also has an influence on the other controls.
Experimentation is the key – please start with these
controls set to mid position.
DFX MIX
– This controls the amount of DFX signal from
the on-board digital reverb circuit that is mixed with the
direct preamp signal. This is footswitchable on or off when
using the above mentioned footswitch.
