For over 40 years the Marshall name has been synonymous
with the greatest guitar tones in music. We have worked hand
in hand with guitarists from all levels throughout the world to
maintain and improve that special ingredient, ‘The Marshall
Sound.’
Our range of effects pedals gives the opportunity to augment
the classic Marshall tone to add Marshall character to a guitar
set-up.
WARNING
Do not expose the apparatus to rain or moisture. Do not expose
the apparatus to dripping or splashing. No objects filled with
liquids should be placed on or near the apparatus. Do not use
this apparatus near water.
Clean only with dry cloth.

All our pedals are made with the same utmost attention to
quality, in both materials and manufacture as our world
renowned amplifiers, cabinets and combos, in order to provide
you with optimum reliability and tone.
I would like to wish you every success with all of your musical
endeavours and also your new Marshall effects pedal, which I
am sure you will find a pleasure to play for many years to
come.
Heed all warnings.
Follow all instructions.
Keep these instructions.

Introduction
Setting Up
Compression is perhaps one of the most useful and versatile
effects available to any guitarist who is interested in improving
their tone.
The attack control modifies the dynamic response of the guitar
signal (the effect of plucking a string) and allows you to
achieve a range of effects from rounded and mellow to
percussive and funky.
The Compressor also features an Emphasis control which
allows you to assign compression and target the frequencies
you want to compress. This means that you can, for example,
tighten up or compress your bass notes and let your treble
notes ring out.
The Compressor features a passive bypass for the main signal
path to ensure complete tonal integrity and has a quality of
tone matched only by its versatility.
Here follows a complete run down of The Compressor’s
features for your information. We have also enclosed a
number of suggested settings to help guide you. It should be
remembered though that these are only suggested settings
and you should really take the time to experiment.
Though the Marshall Compressor can produce traditional type
effects it is also ideally suited to the player who wants
something a little bit different. So take the time to explore the
sonic avenues opened to you by the Compressor, you won’t be
disappointed.

Always use good quality shielded leads.
Always use 9V regulated DC supply with centre negative.
Although it may seem obvious the first action in achieving a
good effected sound (be it duration / compression etc.) is to
find the perfect bypassed sound. This will then allow the
correct level to be set with the effect unit to allow a cut or
boost in volume and a realistic tone.
On clean channels it is advisable to set the gain (or volume)
to a setting of no less than one quarter maximum so as not to
get unrealistic results due to any volume dependent tonal
shaping on the amplifier preamp.
As is inherent in circuits of this type the increase in gain at
low signal levels inevitably leads to unwanted extra noise as
the circuit gain is maximum when the signal level is
minimum. Many players overcome their problem with
discerning use of a swell pedal or simply utilising the bypass
footswitch during performance.

This is the output of The Compressor and is for connection

ENGLISH
The purpose of the Compressor pedal is primarily to allow you
to modify the sustain and attack of your guitar sound. Using
classic variable gain techniques the Compressor will provide
masses of clean sustain, which you can utilise whatever your
style. The Compressor pedal senses the level of the incoming
guitar signal and as the signal level decays the gain of the
internal circuitry is boosted to provide extra level and hence
sustain.

4. DC Input
For input of a 9V DC adaptor (as previously described) should
you not wish to use batteries.
5. LED
Indicates when The Compressor is in operation.
6. Attack
This dictates how quickly compression comes in after pick
attack. With this set at minimum you will get a rounder more
spongy tone. As you increase the Attack the sound will get
sharper and more metallic, which is ideally suited for funky
styles.

7. Compression
This adjusts the amount of compression. The more you add
compression, the more you iron out the peaks and troughs in
your sound. This increases the amount of sustain and makes
for a smoother guitar tone.

Trouble Shooting
The Compressor allows you to specify which end of the aural
spectrum you wish to compress. Select “Hi” if you would like
to emphasise the treble in your tone to get that real twang and
to compress the bass. This is useful for tight funky low note
riffs with stabbing bright chords. Turning toward ‘Lo’ gives
maximum treble compression and hence a ‘Lo’ emphasis.
Battery Replacement
