BEFORE GOING ANY FURTHER
WARNING! IMPORTANT SETUP INFORMATION
Ensure  that  the  specic  mains  input  voltage  rating  that  your  amplier  has  been 
manufactured for matches your electricity supply. This is indicated on the rear panel of 
the amplier.
Your  amplier  is  provided  with  a  detachable  mains  (power)  lead,  which  should  be 
connected to  the MAINS  INPUT socket on the  rear panel  of the  amplier (#24  in this 
manual) before the mains electricity outlet.

MST modelling recreates the tonal and sonic characteristics of some of the most successful 
and respected amplier preamps from the past fty plus years.
JTM45™
The JTM45 was the rst Marshall amplier. It was made in 1962 by Jim Marshall and his 
small team of engineers in a workshop at his music store in Hanwell, London. This 30 Watt 
two  channel  amplier  began  a  revolution  that  changed  forever  the  sound  of  rock  and 
blues music.  The JTM45 is still made today as part of the Vintage Re-Issue™ Series and 
Handwired™ Series. 
1962 Bluesbreaker™
The 1962 Bluesbreaker was the rst combo made by Marshall. Launched in 1965, it had 
two 12” speakers with an output of 30 Watts. The 1962 was famously used by Eric Clapton 
on the inuential blues album ‘John Mayall’s Bluesbreakers’ in 1966 – hence the 1962’s 
‘Bluesbreaker’ nickname. The 1962 Bluesbreaker is still made today as part of the Vintage 
Re-Issue Series™ and Handwired™ Series. 
1959™ Plexi™
To the minds and ears of many, the 100 Watt Super Lead heads of the mid to late 1960s are 
the holy grail of great rock tone. Being non-master-volume, when cranked, the 1959 power 
valves overdrive producing highly responsive, harmonically rich tones. The 1959 amplier 
is still made today as part of the Vintage Re-Issue Series™ and Handwired™ Series.  
JCM800 2203™
The 2203 is one of the most important ampliers Marshall has ever made. It evolved in the 
‘70s from the JMP and 1959 Plexi heads. In the ‘80s the 2203 became the JCM800 2203 
we know today: a straightforward single channel amplier that was favoured by the heavy 
metal scene that dominated much of that decade. Its popularity remained well into the ‘90s 
with the emergence of Grunge and Britpop, and it’s still revered today and is considered 
the benchmark by which modern all metal ampliers are measured.  
JCM2555™ Silver Jubilee™
The 25/50 Silver Jubilee Series was created in 1987 to celebrate the 25th anniversary of 
the founding of  Marshall Amplication  and  50 years of  Jim Marshall being  in the music 
business. Based on the JCM800 2203 and 2204™ Master Volume models, Silver Jubilee 
ampliers had a special preamp circuit that featured three gain ‘modes’ which were Clean, 
Rhythm  Clip  and  a  switchable  Lead  Channel.  The  2555  was  the  100  Watt  head  in  the 
Jubilee series, which was a limited edition. By popular demand the JCM2555 was re-issued 
as the 2555X™ in 2015. 
JCM2000™ DSL100™
Launched in 1997, the JCM2000 Dual Super Lead’s ‘dual mode’ design meant that guitarists 
could  choose  either  a  Clean  or  Crunch  tone  from  the  Classic  Gain  Channel,  whilst  the 
Ultra Gain Channel provided two lead sounds: Lead 1 & Lead 2. This tonal versatility was 
aided by the Deep and Tone Shift features. It is the JCM2000 DSL100’s tonal range and 
versatility that made it massively popular in its day, so much so, that its legacy lives on in 
the current DSL Series.

JVM410H™
When the JVM410H launched in 2006 it caused quite a stir. This 100 Watt head is an all-
valve tonal monster  that  has four  channels, each with  three modes:  Green,  Orange and 
Red, offering guitarists a range of 12 unique tones. Each mode recongures the channel 
gain stages in order to develop different amounts of gain and tone. The JVM410H’s vast 
tonal spectrum makes it the most versatile amplier Marshall has ever made, used by many 
professional players.

GETTING STARTED
To begin using CODE:
• Ensure that the power ON/OFF switch is set to the OFF position (#14 in this manual). 
• Connect the supplied power cord to the MAINS INPUT (#24 in this manual) before 
    plugging into the mains electricity supply. 
• If using the CODE100H head, connect the supplied speaker cable to the speaker cabinet    
and to the SPEAKER jack socket on the amplier’s rear panel (#26 in this manual). 
• Plug your guitar cable into the amplier INPUT jack socket (#2 in this manual). 
• Set the MASTER volume control to zero (#8 in this manual). 
• Turn the amplier ON using the ON/OFF switch. 
• Gradually turn the MASTER up to your desired volume level. 
• Turn the PRESET selector to explore your CODE amplier’s factory Presets 
    (#9 in this manual).
POWER AMPLIFIERS
MST modelling recreates four classic and vintage valve power output topologies. A valve 
power stage is a vital part of an all-valve amplier’s sound and its tonal character. 
SPEAKER CABINETS
Marshall speaker cabinets are perhaps as famous as Marshall ampliers. The iconic 4 x 12” 
design has changed little since Jim Marshall designed the rst one in 1965. Since then the 
Marshall 4 x 12” has become the touchstone for all other speaker cabinets. MST modelling 
recreates the sonic characteristics of eight classic Marshall speaker cabinets, including a 
variety of 4 x 12”, 2 x 12” & 1 x 12” speaker congurations. Marshall speaker cabinets differ 
not only in their speaker congurations, but in the speakers that they use, how they are 
wired and the size of the cabinet.

2. INPUT
Use  this  jack  socket  to  connect  your 
guitar  to  the  amplier.  Use  a  good  quality 
screened/shielded  guitar  cable  to  help 
prevent noise interference.  
3. GAIN
Controls the amount of GAIN introduced to 
a Preset. The  higher the GAIN,  the  harder 
the preamp is driven.
4. BASS
Turning  the  BASS  control  will  adjust  the 
warmth and low-end depth of your sound.
5. MIDDLE
Adjusting the MIDDLE control will vary the 
amount of body in your sound by boosting 
or cutting midrange frequencies.

Increasing  the  TREBLE  will  make  your 
sound  brighter  and  more  cutting.  Turning 
the TREBLE down will decrease tonal edge 
and make the sound softer. 
7. VOLUME
Controls the volume level within a selected 
Preset.
            Because GAIN, BASS, MIDDLE, TREBLE  
             & VOLUME are stored as part of a Preset, 
these panel tone controls only become active 
when they are used. This means that until 
they are turned their position is not related to 
their setting within a Preset. When you turn 
a tone control it becomes active. The display 
screen will show its current setting and the 
stored setting.
             When a GAIN, BASS, MIDDLE, TREBLE 
             or VOLUME control is activated the 
EXIT/STORE  LED  will  ash  red to  show  that 
the Preset’s stored settings have changed.

15. PRE FX
This is where you will nd FX that would typically plug into a conventional amplier setup 
between the guitar and the amplier’s input. These FX would typically be in pedal form, 
and also known as ‘stompboxes’. The ‘stompbox’ FX in the PRE FX section are:
Compressor
Compressor affects an audio signal’s dynamic range. CODE’s compressor decreases, 
or ‘compresses’, any part of your guitar sound that peaks above a certain threshold. 
Any  part  of  your  guitar  sound  that  remains  below  the  threshold  is  unaffected. 
Compressor can add clarity and consistency to your guitar sound whether clean or 
overdriven. Compressor’s editable parameters are:

ENGLISH
PARAMETER VALUE RANGE DESCRIPTION
Tone 0 - 10 Adjusts the Compressor’s higher and lower 
frequencies.
Ratio 0 - 10 Controls how much Compression is applied to a signal 
above the threshold.
Compression 0 - 10 Adjusts the point at which Compression is applied to 
the signal.
Level 0 - 10 Controls the overall volume level of the Compressor.
Distortion
CODE’s  stompbox  Distortion’s  three  Modes  simulate  solid-state  Distortion  and 
Overdrive  FX  pedals.  GUV  Mode  is  a  Marshall  Guv’nor™  with  Drive  and  Tone 
controls.  ODR  &  DIS  Modes  provide  avours  of  classic  overdrive  and  distortion 
stompboxes.  Stompbox Distortion  is  particularly  effective  when  used  with  classic 
and  vintage  MST  preamp  models  to  provide  more  drive  and  sustain.  Distortion’s 
editable parameters are:

Pitch Shifter
Pitch  Shifter  generates  chromatic  harmonies  with  the  ability  to  ne  tune.  This 
enables you to pitch up or down to produce octaves or 3rd, 4th or 5th harmonies. 
Pitch  Shifter  can  also  produce  more  discordant,  quirkier  sounds.  Pitch  Shifter’s 
editable parameters are:
PARAMETER VALUE RANGE DESCRIPTION
Semitone -12 to +12 Selects the pitch of the generated note chromatically 
from  an  octave  below  to  an  octave  above  the  note 
played.
Fine Tune -50 to +50 Fine tunes the pitch of the generated note.
Regeneration 0 - 10 Adjusts the percentage of the signal fed back into the 
Pitch Shifter. Set to zero for a single pitch shifted tone.
Mix 0 - 10 Adjusts the balance between the guitar signal and the 
generated note.
Auto Wah
Auto Wah is a dynamic lter, similar to a Wah Wah pedal. A Wah Wah pedal has a 
‘rocker’ footplate to control the frequency at which the lter operates. Auto Wah has 
no ‘rocker’ footplate, so in ENV Mode the rocker automation responds to input level.  
In LFO Mode the rocker motion is fully automated. Auto Wah’s editable parameters 
are:
PARAMETER VALUE RANGE DESCRIPTION
Mode ENV & LFO Envelope Filter & Low Frequency Oscillator.
Frequency 0 - 10 Controls  the  resting  frequency,  or  fully  closed  posi-
tion,  of  the  Wah,  thereby  setting  how  far  the  lter 
opens when playing.
Sensitivity 0 - 10 ENV Mode: Controls how much the Wah opens in 
relation to the pick attack.
LFO Mode: Controls  the  speed  at  which  the  Wah 
opens and closes. Set to zero and Auto Wah acts as a 
xed rocker Wah.
Resonance 0 - 10 Adjusts  the  magnitude,  bandwidth  and  shape  of  the 
lter’s resonant peak.

16. AMP
AMP is short for preamp. MST modelling faithfully recreates classic and modern Marshall 
valve tones as well as other famous valve amp tones. Each AMP model creates an authentic 
preamp setting. The MST preamp models are classied into three groups: Clean, Crunch & 
Overdrive. 
Your CODE amplier’s MST preamp models are:
The Natural preamp is designed to be used with external FX without the tonal 
colour of an MST modelled preamp. It provides EQ for tonal shaping and access 
to the Gate.
If the noise Gate is applied, when your sound level drops below the set threshold 
it will activate, preventing any signal below that threshold from passing through. 
It progressively attenuates the guitar signal, following its dynamics, to suppress 
unwanted noise.

Chorus
Chorus and Vibrato FX apply a subtle pitch variation to the guitar signal taking your 
sound from shimmering, delicate undulations to full on wobble. This can add depth 
and width to clean sounds and fatten up solos. Chorus’s editable parameters are:
Phaser
Phaser  uses  all-pass  lters  to  shift  the  guitar  signal  very  slightly,  modulating  the 
shifted, or phased, signal in relation to the original signal produces the classic Phaser 
sound - great for tight funky lines, sweeps and swells. Phaser’s editable parameters
