Designer's Introduction
Welcome to the Albion Musical Instruments AG40DFX
and AG80DFX combo amps. The basic topology of these
amps follow that of the other amps in the AG range –
i.e. unique high-voltage FET and Valve based preamp
circuitry and sweet sounding solid-state power amps.
What these two amps have over their AG brothers is the
in-built 16 program digital effects system giving these
amps a whole new sonic dimension. I hope that you enjoy
WKHVRQLFÀH[LELOLW\RI\RXUQHZAlbion amp and get many
years of playing from it.
Thank you

of circuit gives great valve tone, as it should because it
is pretty much a valve circuit. The special high voltage
FET that we use is the closest electronic device to an
actual valve, but without some of the drawbacks of using

also has some “tweaks” that lead to a very convincing
valve-like tone.
The AG40DFX uses a 12 inch loudspeaker designed
to provide a very full and satisfying tone from its mono

out of place at home, in the studio or on the stage.

The output of the AG40DFX can also be plugged into
another loudspeaker cabinet, bypassing the internal
loudspeaker. Plugging into a bigger cabinet widens the
tone available to something rather special.
The AG80DFX has a full two channel control line-up

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
³QRW YHU\ JRRGFDEOH´ FDQDFWXDOO\ EHRIEHQHILW IRU DQ
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
JXLWDU,ISRVVLEOHH[SHULPHQWWRWU\DQG¿QGZKDWVXLWV\RX
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
DUXOHRIWKXPE6LQJOHFRLO W\SH JXLWDUVKDYHOHVVRXWSXW
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.

things, the better the headphone the better the sound.
POWER SWITCH AND INDICATOR – The power
switch and its associated “ON” indicator controls the
mains electricity supply into your amplifier. It is “best
practise” to turn your amplifier OFF when not using it, if
for no better reason than not using the power and helping
to protect the environment! The markings of “0” and “1”

LOUDSPEAKER OUTPUT – The output jack socket
mounted on the rear panel of the AG40DFX allows the
amplifier to be connected into an external loudspeaker
unit. When doing this the internal 12 inch loudspeaker

between 8 ohms and 16 ohms only
Great sounds can be achieved using other guitar speaker
cabinets, especially running into a 4x12” cabinet. Using
a good speaker system brings out the very impressive
sound capabilities of the AG40, making it into an even
more impressive 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
¿QHWXQHGZLWKWKH(4±WU\WXUQLQJXSWKH0,''/(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

to each of the two channels and also the mixing of the

as a rhythm drum machine. Please use a standard 3.5mm

HP OUT – This 3.5mm socket is the output to feed into
headphones for silent practise. Any standard 16 ohm
stereo headphones can be used, although as with all
things, the better the headphone the better the sound.
On the AG80DFX the headphone output is fed from
an intricate active speaker emulating filter network to
produce a more accurate “guitar speaker” sound through
headphones. This circuit is placed before the power

switching to Mute gives you silent performance.
POWER SWITCH AND INDICATOR – The power
switch and its associated “ON” indicator controls the
mains electricity supply into your amplifier. It is “best
practise” to turn your amplifier OFF when not using it, if
for no better reason than not using the power and helping
to protect the environment! The markings of “0” and “1”
comply with international standards – 0=off, 1=on.

A WORD OF ADVICE about fuses – if a fuse blows it is
usually for a very good reason, it could be anything from a
voltage spike on the mains power, to a serious malfunction
of your amplifier. Fuses are there for your protection –
treat them with respect, and never replace with the wrong
value.
