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.

The differences between the Normal and Overdrive
channels are worth understanding. The Normal channel
is designed to give predominantly great clean to slightly
overdriven crunch sounds. To achieve this the EQ circuit is
placed before the channels gain circuits, thus the EQ sort
of works like 3 frequency dependant gain controls. When
the Normal gain control is set close to, or at, maximum
then the post EQ gain circuits get overdriven and can be
¿QHWXQHGZLWKWKH(4±WU\WXUQLQJXSWKH0,''/(FRQWURO
for a very “singing” tone.
The Overdrive channel works slightly differently. For a
start the circuit is designed for much more distortion
and overdrive, and is voiced to focus in on the best
frequencies that overdrive works at. Alternatively to the
Normal channel, the EQ on the Overdrive channel is
placed after the gain and distortion circuitry – thus the EQ
tailors the tone of the distortion.
GAIN
– This control determines the amount of signal that
the preamp circuit has to produce the overdrive sound.
Low settings will produce clean tones; whilst higher to
maximum settings will produce overdriven tones. The
intensity and voice of these will change from normal to
overdrive channels.
VOLUME
– This quite simply controls the output of the
sound generated by the 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
AG80DFX 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.
DFX SELECT
– This rotary encoder selects which one
of the 16 programs of digital effects that you want to use.
Each program illuminates the associated number on the
