The Marshall CODE50 is a versatile 50-watt digital modelling guitar amplifier designed to place a wide range of classic and contemporary Marshall sounds into one portable combo.

Powered by Marshall-Softube modelling technology, the CODE50 lets you combine digital preamp, power-amplifier and speaker-cabinet models to create sounds inspired by some of Marshall’s most celebrated amplifiers. From warm vintage cleans and blues breakup to classic-rock crunch and modern high-gain distortion, it provides an extensive tonal platform for practice, recording, rehearsals and performance.

The amplifier includes 100 editable presets and 24 digital effects, with up to five effects available simultaneously. Sounds can be created directly from the top control panel or managed wirelessly through the Marshall Gateway app on a compatible mobile device.

Bluetooth audio streaming, an auxiliary input and an emulated headphone output make the CODE50 particularly practical for playing along with music and practising quietly. Its custom 12-inch speaker and 50-watt output also give it considerably more depth and projection than a small desktop practice amplifier.

This Ex-Display example has been demonstrated in the Fair Deal Music showroom and professionally checked for correct operation before sale.

Why Choose the Marshall CODE50?

A Complete Collection of Marshall-Inspired Sounds

The CODE50 uses Marshall-Softube modelling to recreate the character of different amplifier stages and speaker cabinets.

Rather than limiting you to one fixed amplifier voice, it lets you select and combine:

• Preamplifier models

• Power-amplifier models

• Speaker-cabinet models

• Pre-effects

• Modulation effects

• Delay effects

• Reverb effects

This modular approach makes it possible to build a sound around the needs of a particular song, guitar or playing style.

You can explore tones inspired by vintage British amplifiers, classic Marshall crunch, modern high-gain designs and cleaner contemporary sounds without needing a room full of separate amplifiers and cabinets.

100 Editable Presets

The CODE50 contains 100 built-in presets covering a broad range of clean, overdriven, distorted and effects-based sounds.

Presets provide an immediate starting point for:

• Clean rhythm playing

• Blues

• Classic rock

• Indie and alternative music

• Punk

• Hard rock

• Metal

• Ambient guitar

• Lead playing

• Effects-based sound design

Each preset can be edited and stored, allowing the amplifier to be adapted to your own guitar, pickups and preferred playing style.

This is especially useful for players who need several sounds during a rehearsal or performance. Instead of manually changing every control, a prepared preset can recall the required amplifier model, cabinet simulation and effects configuration.

24 Built-In Digital Effects

The CODE50 includes 24 digital effects, with up to five effects available simultaneously.

The effects are arranged across several sections, allowing different types to be combined within one preset.

Available effect categories include:

• Compression

• Distortion and drive

• Auto-wah

• Pitch effects

• Chorus

• Flanger

• Phaser

• Tremolo

• Delay

• Reverb

This provides enough flexibility to create straightforward practice tones, complete stage-ready sounds and more experimental textures without immediately requiring a separate pedalboard.

Five Effects at Once

Up to five effects can be used simultaneously within a preset.

A typical sound might combine:

• Compression or drive before the amplifier model

• Chorus or phaser

• Delay

• Reverb

• A selected amplifier and cabinet configuration

This lets you build a complete sound rather than being restricted to one effect at a time.

The effects can also be switched or adjusted individually, helping you understand how each part of the signal chain changes the overall tone.

Marshall Gateway App Control

The Marshall Gateway app provides wireless control over compatible CODE amplifier functions.

Using a suitable iOS or Android device, you can:

• Browse the amplifier’s presets

• Edit preset settings

• Adjust Bass, Middle, Treble, Gain and Volume

• Select modelling stages

• Activate and edit effects

• Store customised sounds

• Manage a library of personal presets

The app provides a larger visual interface than the amplifier’s onboard display, making detailed editing quicker and easier.

All essential sounds can still be accessed from the amplifier itself, so the CODE50 does not depend on a mobile device for normal operation.

Bluetooth Audio Streaming

Bluetooth connectivity allows compatible music to be streamed through the amplifier.

This is useful for playing along with:

• Favourite songs

• Backing tracks

• Online lessons

• Drum loops

• Practice exercises

• Recorded band material

The streamed audio plays through the amplifier alongside the guitar signal, creating a convenient all-in-one practice setup without requiring a separate speaker system.

CODE Presets Community

The CODE platform supports downloading and sharing compatible presets through Marshall’s CODE Presets service.

This lets players explore sounds created by Marshall and other CODE users, providing useful starting points for different artists, genres and playing styles.

Downloaded sounds can be adjusted to suit your own guitar and stored as part of a personal preset library.

Powerful 50-Watt Output

The CODE50 provides 50 watts of digital amplification through a custom 12-inch speaker.

This gives it greater depth, low-frequency response and projection than a small bedroom amplifier.

The output is suitable for:

• Home practice

• Guitar lessons

• Recording

• Rehearsals

• Playing with other musicians

• Smaller live performances

• Use as a stage monitor when appropriately reinforced

Final performance suitability will depend on the band, drummer, venue and required clean headroom.

Custom 12-Inch Speaker

The amplifier contains one custom-designed 12-inch speaker rated at 50 watts and 4 ohms.

A full-sized 12-inch guitar speaker provides:

• Greater low-frequency body

• Fuller chord reproduction

• Stronger projection

• A more physical playing response

• Improved depth for driven sounds

• Better coverage than many compact practice amplifiers

The speaker is designed to reproduce the variety of amplifier and cabinet models available within the CODE system.

Straightforward Physical Controls

Although the CODE50 offers extensive digital flexibility, its main controls remain familiar to guitarists.

Dedicated controls include:

• Gain

• Bass

• Middle

• Treble

• Volume

• Master Volume

Individual buttons provide access to the modelling and effects sections, while the display and Edit control allow deeper parameters to be adjusted.

This gives you the choice of making quick physical changes or carrying out more detailed editing through the Gateway app.

Emulated Headphone Output

The 3.5mm headphone output supports quieter practice and mutes the internal speaker when connected.

Its emulated response is designed to provide a more natural guitar-amplifier sound through headphones than an untreated direct signal.

This is particularly useful for:

• Evening practice

• Shared homes

• Flats and student accommodation

• Quiet warm-ups

• Learning songs privately

• Practising without disturbing others

Headphones require a 3.5mm connection or an appropriate adaptor.

Auxiliary Input

A wired audio source can be connected through the 3.5mm auxiliary input.

This offers an alternative to Bluetooth and works well with compatible:

• Phones

• Tablets

• Computers

• Music players

• Drum machines

• Practice devices

The input is useful when a stable wired connection is preferred or when the source device does not support Bluetooth.

Optional Foot Control

Compatible CODE foot controllers are available separately.

Foot control can make it easier to move through presets while playing, reducing the need to reach for the amplifier between songs or sections.

This is especially valuable for rehearsals and performances where several preset sounds are required.

No Valve Maintenance

The CODE50 uses digital and solid-state technology, so it does not require valve replacement, warm-up time or bias adjustment.

It can be switched on and used immediately, making it practical for frequent home practice, teaching and rehearsal use.

Why Choose a Digital Modelling Amplifier?

A modelling amplifier combines multiple amplifier voices, speaker simulations and effects within one enclosure.

This provides several advantages for players who want variety without purchasing a large collection of equipment.

The CODE50 can replace or reduce the need for:

• Several different practice amplifiers

• Multiple drive pedals

• Separate modulation pedals

• Delay and reverb pedals

• A dedicated backing-track speaker

• Complex preset switching systems

A modelling amplifier is particularly useful when learning different genres, recording ideas or performing songs that require contrasting guitar sounds.

Unlike a traditional single-channel valve amplifier, the CODE50 can move between a bright clean tone, vintage crunch, heavily distorted rhythm sound and ambient lead preset without manually rebuilding the entire signal chain.

Who Is It For?

Beginner Guitarists

The factory presets provide immediate usable sounds without requiring a detailed understanding of amplifier circuits or effects.

As the player develops, the CODE50 also provides an accessible way to learn how Gain, EQ, amplifier models, cabinet simulations and effects shape the sound.

Developing Players

The wide range of tones allows developing musicians to explore different musical styles without continually replacing their amplifier.

The auxiliary input, Bluetooth streaming and headphone output also support structured practice at home.

Experienced Home Guitarists

Experienced players can create and store customised sounds, use the Gateway app for deeper editing and download additional presets from the CODE community.

Recording Musicians

The broad range of repeatable presets makes the CODE50 useful for capturing ideas, demos and layered guitar arrangements.

Different sounds can be recalled without resetting every control between takes.

Guitar Teachers

The amplifier’s presets make it easy to demonstrate contrasting sounds during lessons, while Bluetooth and auxiliary connectivity support backing tracks and learning material.

Cover-Band Guitarists

Players covering multiple genres can prepare presets for different songs and move between clean, crunch, lead and effects-based sounds more efficiently.

Players Who Do Not Want a Large Pedalboard

The onboard effects provide compression, drive, modulation, delay and reverb within one amplifier.

This creates a complete rig with fewer cables, power supplies and separate pedals.

Players with Limited Space

The CODE50 combines amplification, speaker modelling and effects in one portable enclosure, making it more practical than maintaining several amplifiers and cabinets at home.

Understanding the CODE50 Signal Chain

The CODE50 creates each preset from several virtual sections.

Pre-Effects

The pre-effects section applies compatible effects before the selected amplifier model.

These can include compression, drive and other effects that traditionally sit near the beginning of a guitar signal chain.

Preamplifier Model

The preamplifier model defines much of the preset’s basic gain structure and tonal character.

This is where you can move between cleaner sounds, classic Marshall crunch and higher-gain voices.

Power-Amplifier Model

The power-amplifier section changes the response and feel of the selected preamp.

Different power-stage models can alter perceived punch, compression, headroom and harmonic character.

Speaker-Cabinet Model

The cabinet model simulates the tonal effect of different speaker and enclosure designs.

This has a major influence on bass response, midrange character and upper-frequency detail.

Modulation

Modulation effects can add movement and width through chorus, flanger, phaser and tremolo-style sounds.

Delay

Delay produces echoes and repeats, from subtle thickening to more pronounced rhythmic or ambient effects.

Reverb

Reverb adds a sense of space around the guitar, ranging from restrained room ambience to larger and more atmospheric sounds.

Creating Useful CODE50 Sounds

Clear Practice Tone

Select a cleaner amplifier model with restrained Gain.

Keep effects minimal and adjust Bass, Middle and Treble to suit the guitar.

This creates a clear sound for chord practice, scales and technique work.

Classic Marshall Crunch

Choose a vintage or classic Marshall-style model and raise Gain to a moderate level.

Add enough Middle for body and projection, then use a small amount of reverb for depth.

Hard-Rock Rhythm Sound

Select a higher-gain model, control excessive Bass and keep enough Middle for the guitar to remain present.

A small amount of compression or drive can create a tighter attack.

Sustaining Lead Preset

Use increased Gain, a mid-forward EQ and a suitable combination of delay and reverb.

Set the preset volume carefully so the lead sound sits above the rhythm presets.

Ambient Clean Sound

Choose a clear amplifier model and combine modulation, delay and reverb.

Keep Gain low to preserve note definition as the effects build around the guitar.

Backing-Track Practice Setup

Connect a music source through Bluetooth or the auxiliary input.

Balance the playback volume from the connected device, then use the amplifier controls to position the guitar clearly over the track.
