Designer's Introduction
Welcome to Albion Musical Instruments AG40R
and AG80R combo amps. Having designed many
competitively priced amps, many of them of them have
been destined to be award winning and certainly “classics”
in their own right, I realised that I had somewhat of a
challenge in front of me when creating the AG range. “How
do I beat what I have done before?”, “How can I raise
WKHSUR¿OHRIORZHUFRVWSUDFWLVHDQG³ZHHNHQG´DPSVWR
make them into really serious amps?”, I realised there was
quite a massive challenge in front of me! I think that what I
have done with the AG range actually surpasses even my
expectations. I hope that you agree with me.
Thank you

is supplied with a high voltage dc supply, again pretty
unique in small guitar amplifiers. This combination 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 an

solid state power amp circuit that also has some “tweaks”
that lead to a very convincing valve-like tone.
The AG40R uses a 10 inch loudspeaker professionally
designed to provide a very full and satisfying tone in a
nicely proportioned compact cabinet. Whilst the AG80R
is provided with a seriously beefy and tuneful 12 inch
speaker, again the cabinet design leads to an easily
transportable package that doesn’t look, or sound, out of
place at home, in the studio, or on the stage.
The AG40R has a two channel control line-up of (normal

The output of the AG40R 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 AG80R has a full two channel control line-up of

a 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

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

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.

CAUTION! There are no user serviceable parts mounted

personnel.
Rear Panel
LOUDSPEAKER OUTPUT – the output jack socket
mounted on the rear panel of the AG40 allows the
amplifier to be connected into an external loudspeaker
unit. When doing this the internal 10 inch loudspeaker
is disconnected. The amplifier will feed into a load of
between 8 ohms and 16 ohms only.
DO NOT USE ANY OTHER LOAD IMPEDANCE!
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.
MAINS INPUT – the mains input receptacle allows for
the connection of the mains power cord, and also houses

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!

The differences between the Normal and Overdrive
channels is 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 fine
tuned with the EQ – try turning up the MIDDLE control 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 also 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 an almost 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
independently on both the Normal and Overdrive channels.
The AG80 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

WARNING! USE THE CORRECT REPLACEMENT
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

things, the better the headphone the better the sound. On
