MARSHALL AMPLIFIER HISTORY
MST modelling recreates the tonal and sonic characteristics of some of the most successful and respected amplifier preamps from the past fifty plus years.
JTM45™
The JTM45 was the first Marshall amplifier. 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 amplifier 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 first 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 influential 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 amplifier 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 amplifiers 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 amplifier 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 amplifiers 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 Amplification and 50 years of Jim Marshall being in the music business. Based on the JCM800 2203 and 2204^TM Master Volume models, Silver Jubilee amplifiers 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 reissued as the 2555X^TM 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.

MARSHALL AMPLIFIER HISTORY (CONT.)
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 reconfigures 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 amplifier Marshall has ever made, used by many professional players.
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 amplifier's sound and its tonal character.
SPEAKER CABINETS
Marshall speaker cabinets are perhaps as famous as Marshall amplifiers. The iconic 4 x 12" design has changed little since Jim Marshall designed the first 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 configurations. Marshall speaker cabinets differ not only in their speaker configurations, 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 amplifier. 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.
6. TREBLE
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 flash red to show that the Preset's stored settings have changed.

14. PRE FX
This is where you will find FX that would typically plug into a conventional amplifier between the guitar and the amplifier's input. These FX would typically be in pedal form, and also known as 'stompboxes'. The 'stompbox' FX in the PRE FX section are:
'STOMPBOX' FX

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:
| 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 flavours 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:
| PARAMETER | VALUE RANGE | DESCRIPTION |
| Mode | GUV, ODR & DIS | Marshall Guv'nor, Classic OD pedal & Classic Distortion pedal. |
| Drive | 0 - 10 | Controls the amount of Overdrive or Distortion applied to the signal. |
| Tone | 0 - 10 | Adjusts the amount of upper mid and higher frequency content in the Overdrive or Distortion before the signal reaches the amplifier panel tone controls. |
| Level | 0 - 10 | Controls Distortion's overall volume level. |

'STOMPBOX' FX

Auto Wah
Auto Wah is a dynamic filter, similar to a Wah Wah pedal. A Wah Wah pedal has a 'rocker' footplate to control the frequency at which the filter 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 position, of the Wah, thereby setting how far the filter 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 fixed rocker Wah. | |
| Resonance 0 - 10 | Adjusts the magnitude, bandwidth and shape of the filter's resonant peak. | |
Pitch Shifter
Pitch Shifter generates chromatic harmonies with the ability to fine 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. | ||

15. 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 classified into three groups: Clean, Crunch & Overdrive.
Your CODE amplifier's MST preamp models are:
PREAMP MODELS

CLEAN
| JTM45TM | JTM45 2245 on a clean setting. |
| CL DSL | DSL100H on the Classic Gain Channel, Clean setting. |
| CL American | Classic American pure-valve sound. |
| CL JVM | JVM410H on the Clean Channel in Green Mode. |
| Acoustic Simulator | Simulates the sound of an electro-acoustic guitar. |
CRUNCH
| BluesbreakerTM | 1962 Bluesbreaker combo overdriven. |
| PlexiTM | 1959SLP Overdriven. |
| CR American | Classic American valve overdrive. |
| JCM800TM | JCM800 2203 overdriven (high sensitivity input). |
| ‘50s British | Classic British valve combo overdrive. |
OVERDRIVE
| OD JVM | JVM410H on OD1 Channel in Red Mode. |
| OD DSL | JCM2000 DSL Lead 2 Channel. |
| OD American | Classic American higher gain overdrive. |
| OD Silver Jubilee | JCM2555 Silver Jubilee Lead Channel. |
NATURAL
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.
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.
PARAMETER VALUE RANGE DESCRIPTION
Threshold 0 - 10 Sets the point at which the Gate begins to close.

| Speed 0 - 10 Controls the rate of the Flanger effect. | ||
| Depth 0 - 10 Adjusts the depth of the Flanger effect. | ||
| Regeneration | 0 - 10 Adjusts the amount of signal that is fed back to the effect input, which makes the Flanger effect sharper. | |
Phaser
Phaser uses all-pass filters 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 are:
PARAMETER VALUE RANGE DESCRIPTION
| Mode CLS & VBE | Classic Phaser & Vibe. |
| Speed 0 - 10 Controls the rate of the | Phaser or Vibe effect. |
| Depth 0 - 10 Adjusts the depth of the | Phaser or Vibe effect. |
| Regeneration | 0 - 10 Adjusts the amount of signal that is fed back to the effect input, which makes the Phaser effect sharper. |
ENGLISH EN
16. MOD (CONT.)
MODULATION FX

Tremolo
The cool sounding Tremolo effect is created by the signal amplitude being modulated up and down. Tremolo can produce a variety of sonic characteristics from delicate shimmer to heavy Tremolo throb. Tremolo's editable parameters are:
PARAMETER VALUE RANGE DESCRIPTION
| Mode VLV & SQR | Valve Tremolo & Square Wave Tremolo. | |
| Speed 0 - 10 Controls the rate of Tremolo oscillation. | ||
| Depth 0 - 10 Adjusts the depth of the Tremolo effect. | ||
| Skew | -50 to +50 | Adjusts the shape of the waveform that is performing the amplitude modulation. The variation of the wave shape across the value range moves between vintage and modern sounding Tremolo. |
