a properly screened “guitar” cable for interconnection.
There are many different makes of guitar cable available,
ranging from fairly inexpensive to ver y 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

benefit for an overly bright single coil guitar by taming
the very high end frequencies. Alternatively, a very low
capacitance cable can help brighten up a muddy sounding
hum-bucker type guitar. If possible experiment to try and
find what suits you and your guitar best. Hopefully your

pedal system then the best advice is to use high quality,
low noise, low capacitance cable from pedals to amp
connection.
NORMAL VOLUME –
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

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

guitars have less output and a brighter sound. Guitars
with Hum-buckers will have a thicker louder sound. Also

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
AG40 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 an 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.
REVERB –
This controls the amount of reverb 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.
