From Jim Marshall
I would like to thank you personally for selecting one
of our Valvestate AVT amplifiers.
Ever since its initial launch in the early 1990’s, the
original Marshall Valvestate technology received
worldwide acclaim and set a new standard in affordable
quality amplification. However, my dedicated team of
designers are constantly looking for methods to make our
amplifiers sound even better. As they are all guitar players
themselves this process has become a passion within the design
department.
As the name Advanced Valvestate Technology (AVT) suggests,
your new amplifier benefits from their research and utilises their
latest circuit innovations, all of which are totally unique to
Marshall. By emulating the feel and response of an all-valve
amplifier even more closely, the AVT range perform brilliantly and
represent yet another major step forward in guitar sound
technology.
Since I first began making amplifiers in 1962, one of the key
factors in our success has been reliability. Therefore, many hours
of exhaustive testing have been carried out in the development
of AVT to ensure that this remains so.
I suggest that you read this manual thoroughly before operating
your new amplifier and keep it in a safe place for future
reference. This will help you to derive maximum enjoyment from
our Advanced Valvestate Technology.
Wishing you every success.
Yours Sincerely,

Introduction

AVT20X Combo Front Panel Features

Welcome to the third and most recent generation of Marshall Valvestate guitar amplifiers - AVT.

1. Input Jack Socket

We first started making the critically acclaimed Valvestate amplifiers in the early 90s and then updated
the original range to the best-selling VS II line in 1996. Our original intention with Valvestate was
simple: to capture the special sound and feel of a Marshall valve amplifier by using solid state
technology. By so doing we knew we could make our unique and highly desirable tones more
affordable and thus more available to many more guitar players. The first two generations of
Valvestate both achieved these goals and have become firm favourites with players and critics alike,
the world over. Now, we have once again redefined what guitarists can expect from affordable
backline amplification. Utilising all the knowledge and experience gained over the years, we proudly
bring you - AVT Series.

Addictive Tone
In this latest generation, not only will you find more, guitarist-friendly features, but more (much more!)
valve-like tone and feel. As with all our amplifiers, we started designing with a clean slate - relying
totally on our experience, skill and tonal history. As all our designers are guitarists in addition to being
exceptional engineers, the aforementioned feel and tone were an absolute priority from the beginning.
In short our goal was to make these amps so enjoyable to play, they are addictive!

Pre-amp Valve Power
In each of the Valvestate range, all the preamp stages are equipped with an ECC83 (a.k.a. 12AX7)
Dual Triode valve. Drawing on our vast experience in this field, we have gone to great lengths to
ensure that this precious device delivers maximum sonic benefit at all settings and volume levels. As
a result, even the AVT clean sounds ring with the bell like harmonics that only a valve pre-amp can
deliver. On the Overdrive channels the ECC83's dual triodes are saturated to their limit, providing the
dynamics and feel worthy of a place in the Marshall hall of fame. The same sort of toneful care and
attention was focused on the all-important power stage of each amp too. Once again we wanted to
ensure that they delivered the warm, musical feel and 3-dimensional sounds that have made our allvalve power-amps world-renowned. We are so proud of the end results of our labour that we felt we
had to coin a new name for the technology used. So, we christened it AVT - Advanced
Valvestate Technology.

5. Tone Controls
The AVT20X is equipped with rotary Bass,
Middle, and Treble controls, all of which work on
both the Clean and Overdrive modes. These
three passive EQ controls are designed to
achieve maximum tonal variation from your
AVT20X and, just like our famous all-valve
amps, are highly inter-dependent on each other.
As a result, the way each one functions
depends on the exact position of the other two
controls. This is especially true of the Bass and
Treble controls in relation to the Middle control.
The lower the Middle control, the more reaction
can be obtained from the others. As tone is very
much down to personal taste, experimentation
and experience is probably the best way of
learning how these three controls will affect your
sound. Some suggested settings are shown
later.

2. Clean/Overdrive selection switch
Your AVT20X has two selectable modes - Clean
and Overdrive. When the switch is ‘out’ Clean is
selected, when it is pushed ‘in’ Overdrive mode
is activated.
The Clean mode of the AVT20X has the warm,
responsive action normally associated with a
valve amp, rather than the relatively sterile, onedimensional sound that is typical of many solidstate type guitar amps. At lower Gain settings
this mode remains very clean but will evolve into
a bluesy/rock type crunch at higher Gain
settings.
When Overdrive is selected it will take you from
mild crunch to aggressive ‘modern’ distortions
and all-points in between. The many sonic
palettes available are dependent on the exact
settings of the front panel controls for Gain,
Volume, Treble, Middle and Bass.

* Points to remember are:
A) The tone and output level coming out of the
guitar is as widely variable as there are guitars
themselves, all guitars are not designed (nor
intended) to be equal. Therefore, amp settings
will vary to suit your guitar and playing style, and
by necessity, are at your discretion. Again, if in
doubt, consult your Marshall dealer for advice.

3. Gain Control
Fire-breathing Babies
This manual covers the AVT20X and AVT50X combos plus the AVT50HX head. Even though these
are the ‘babies’ of the range, they go far beyond the realms of traditional, lower powered amps. These
are all real, fire-breathing Marshall amps in their own right, and, as such, are bestowed with all the
technology, tone, and feel of their higher-powered brethren. As is the case with the entire AVT range,
the loudspeakers used are all custom built by Celestion and have been specifically designed to fully
complement and augment the myriad of sounds generated by our Advanced Valvestate Technology.

This rotary control can best be described as the
sonic ‘brains’ of the amp. At lower settings, with
the Clean/Overdrive switch set to Clean, the
AVT20X will give you a wide range of welldefined clean tones. At higher Gain settings, the
amp will start to ‘crunch up’ into the
aforementioned ‘blues/rock’ type sounds. This
‘crunching up’ is often referred to as ‘break-up’.
When Overdrive mode is selected lower Gain
settings will give you a vintage sounding, valve
distortion while higher settings will produce more
modern, high-gain tones.

B) The tone of your sound is also dependent on
the settings of the ‘tone’ controls, and adjusting
them to taste will further enhance the sonic
textures of your AVT20X. The best way to
achieve your desired settings is to experiment.

6. Reverb Depth Control
Your AVT20X is fitted with an internal spring
Reverb unit. This control affects the mix of the
direct (dry) and Reverb signals - the higher this
control is set, the greater the Reverb depth.

4. Volume Control
7. CD Input Jack Socket

As its name suggests, the Volume control
determines how loud your AVT20X will be by
controlling how much signal is transferred from
the preamp to the power amp. Due to the
remarkable realism of our Advanced Valvestate
Technology, once the Volume control is turnedup past a certain point, the preamp will start to
push the power amp section into creating its

The CD input will take a stereo signal from an
external source, such as a CD or tape player,
and mix it into a mono format. This will allow
you to play along with a pre-recorded signal.
Because this input is after the preamp stage, its
volume has to be controlled from your CD or
tape player.

own, desirable distortion mode - just like an allvalve Marshall amp. When this occurs, the
AVT20X's power amp will start to add musical
harmonics, compression and ‘break-up’ into your
sound.

This is where you plug your guitar into the amp.
In case you are not aware, you must always use
a screened guitar cable, never use an
unscreened speaker lead. Also, for the best
performance this cable should be one of high
quality. If you are in any doubt regarding this,
your Marshall dealer will be more than happy to
help and advise you further.

9. Headphone Jack Socket

5. Channel Push-switch

This jack socket carries a specially treated
output signal from your AVT20X which
accurately emulates the sonic signature of a
guitar loudspeaker. This output can be used in
both live performance and recording situations
to achieve authentic guitar amp tones without
having to use a microphone. Furthermore, if you
wish to mute the loudspeaker, for ‘silent’
recording, then merely insert an unused jack
plug (a short patch cable will do fine) or a set of
headphones into the Headphone socket.

In addition to providing a specially filtered output
signal for a set of headphones, this jack also
disconnects the main loudspeaker, enabling you
to practice in ‘silence’.

Your AVT50X has two channels - Clean and
Overdrive. This switch selects the channel you
desire - ‘out’ for Clean and ‘in’ for Overdrive.
When using the supplied footswitch, the channel
push-switch must be left in the ‘in’ position for
the footswitch to operate.

10. External Speaker Jack Socket
This socket allows you to connect your AVT20X
into an external loudspeaker system, provided it
has an impedance of 8 or 16 ohms. By using
any one of our comprehensive range of
extension cabinets, you will be able to unleash
the massive amount of tonal options that extra
loudspeakers will provide.

The actual volume settings will be dependent on
how loud you want the channel to be, and also
what type of sound you have selected on the
pre-amp. Due to the remarkable realism of our
Advanced Valvestate Technology, once the
Volume control is turned-up past a certain point,
the preamp will start to push the power amp
section into creating its own, desirable distortion
mode - just like an all-valve Marshall amp.
When this occurs, the AVT50X’s power amp will
start to add musical harmonics, compression
and ‘break-up’ into your sound.

2. Clean Gain Control
When the Clean channel is selected, this rotary
control can best be described as the sonic
‘brains’ of said channel. At lower settings, this
control will give you a wide range of well defined
clean tones. At higher settings, this control will
start to ‘crunch up’ the sound of the channel in a
‘blues/rock’ type fashion. This ‘crunching up’ is
often referred to as ‘break-up’.

4. Clean Tone Controls
The AVT50X Clean Channel is equipped with
rotary Bass and Treble controls, with a pre-set
mid ‘scoop’. As is the case with our all valve
amps, these two passive controls are very interdependent on each other. As tone is very much
down to personal taste, experimentation and
experience of the control’s functions is probably
the best way to learn how they will affect your
sound. We would advise spending some time
with these controls to see what suits you best.
Some suggested settings are shown later, to act
as possible starting points.

‘modern’ distortions and all-points in between.
The many sonic palettes available from both
channels are dependent on the exact settings
you choose on the front panel controls for Gain,
Volume and EQ.

B) The tone of your sound is also dependent on
the settings of the ‘tone’ controls, and adjusting
them to taste will further enhance the sonic
textures of your AVT50X.

6. Overdrive Gain Control
When the Overdrive channel is selected, this
rotary control acts as it’s sonic ‘brain’. Lower
Gain settings will give you a vintage sounding,
valve distortion while higher settings will
produce more modern, high-gain tones.

9. Reverb Depth Control
The AVT50X is fitted with an internal spring
Reverb unit. This control affects the mix of the
direct (dry) and Reverb signals - the higher the
control is set, the greater the depth of the
Reverb.

7. Overdrive Volume Control
As its name suggests, this control determines
how loud your AVT50X’s Overdrive channel will
be. The volume setting you choose will be
dependent on both how loud you actually want
to be, and also what type of sound you have set
up on the preamp, i.e. high overdrive settings
will be generating much more preamp output
level than lower, cleaner settings. Due to the
remarkable realism of our Advanced Valvestate
Technology, once the Volume control is turnedup past a certain point, the preamp will start to
push the power amp section into creating its
own, desirable distortion mode - just like an allvalve Marshall amp. When this occurs, the

The specific mains input voltage rating that your
amplifier has been built for is shown on the back
panel. Before connecting for the first time,
please ensure that your electricity supply is

headphones into the Headphone socket.

On all the following suggested settings you will immediately notice how rich and authentic the sounds
are. As you will hear, even on clean settings AVT adds those subtle harmonics and that desirable
compression which only a classic all-valve amp can normally deliver.

2.Loudspeaker Jack Socket
4. FX Return Jack Socket

i. Combo Version (AVT50X)
This socket allows you to connect your AVT50X
into an external loudspeaker system, provided it
has an impedance of 8 or 16 ohms. By using
any one of our comprehensive range of
extension cabinets, you will be able to unleash
the massive amount of tonal options that extra
loudspeakers will provide.

Use a high quality shielded lead to connect the
output of your effects unit to the effects return
jack of the AVT50HX.

5. FX Send Jack Socket
The AVT50X is fully equipped with a Series
effects loop in order to allow you to connect
external effects units to the amplifier. As always,
we recommend you use high quality leads to
ensure you lose none of the tone of the
AVT50X’s direct signal. Connect this output to
the input of your effects unit. Adjust the input
gain of your effects unit so as not to overdrive
its circuitry. Set the effects unit output level to
achieve the same ‘effected volume’ as in
bypass.

ii. Head Version (AVT50HX)
This is where you connect your AVT50X Head to
external loudspeaker cabinets in order to deliver
the extraordinary power that only a Marshall
head can provide.
The AVT50HX is specifically voiced to run into
the AVT412XA / AVT412XB 4x12" compact
cabinet combination. Having said this the
AVT50HX is equally at home driving any one of
our other loudspeaker options, such as the
legendary 1960A/B 4x12" full size cabinets for
example.

!

Funky Clean
A really bright clean which still maintains Mid definition. This is best used in conjunction with a singlecoil neck pick-up or the neck / bridge combination on a humbucker-equipped guitar. Keeping the Gain
control low ensures a clean preamp signal and also helps feed extra treble through to the power
amplifier for additional brightness and cut.

Blues Clean
Here the preamp Gain is increased and what you start to hear is pure, harmonically rich break-up
and compression from the internal Marshall ECC83. Again the neck pick up on a single coil guitar or
the neck / bridge combination on a humbucker-loaded guitar will deliver the warmest tones.

Brit Crunch
Here the advantage of the separate Gain and Volume controls really come into play. Notice how the
Gain is quite low but the Volume is quite high. This is the way the old Marshall crunch sounds of the
late 60’s and 70’s were created - namely by keeping the preamp pretty clean and creating the desired
distortion by driving the power stage hard. With such a setting, when you back off the guitar’s Volume
or pick less heavily, you will feel and hear how the rich, clear tone of the clean sound remains.

MV Crunch
This crunch is reminiscent of the first Marshall Master Volume amplifiers of the much heralded
JCM800 series. The Valve Drive Preamp is driven into mild saturation, creating a big, open overdrive
using the bridge position pick-up, whether single-coil or humbucker.

Screaming Lead
Here the Gain is cranked to the max and the Mids are brought up to fatten the tone of the single
notes. With these settings the rich, natural harmonic overtones that the valve introduces will be very
apparent. Best with the bridge pickup.

6. Footswitch Input Jack Socket
Supplied with your new AVT50X is a Marshall
Channel select footswitch (PEDL-10001). This
plugs into the Footswitch Input Jack Socket.

Heavy, Modern Crunch
Cutting the Mids while heavily boosting the Gain, Treble and Bass gives an aggressive, modern ‘tearyer-face-off’, scooped sound. The bridge humbucker is the one to use here if you truly wanna ride the
lightning... definitely not for the faint-hearted!

WARNING:

Always provide the AVT50HX with a load equal
to, or greater than, 4 Ohms. Using the two
loudspeaker outputs, with cabinets rated at 8
Ohms each, the full 50W of the specially
designed AVT power amplifier will be unleashed.
