Wide Range of Marshall Amplifier Sounds The CODE 25 uses digital modelling to recreate a variety of classic and modern Marshall amplifier characteristics. Rather than being limited to one fixed circuit, players can select different virtual preamps, power-amplifier stages and speaker cabinets. These components can be combined to create clean, crunch, vintage overdrive and modern high-gain sounds. This flexibility makes the CODE 25 suitable for musicians who play several styles or want to experiment with different amplifier characters before committing to a larger traditional rig. Marshall-Softube Modelling Technology Marshall developed the CODE platform with audio-software specialist Softube. Marshall-Softube modelling technology recreates the interaction between the selected preamp, power amplifier and speaker cabinet rather than applying a single distortion effect to every sound. Changing one part of the virtual signal chain can alter the response, gain structure, midrange emphasis and overall feel of the preset. 100 Editable Presets The CODE 25 contains 100 presets covering a broad range of musical styles and playing situations. Factory presets provide immediate access to usable sounds, while every preset can be edited and stored. Players can create dedicated settings for different guitars, songs, practice routines and recording projects. Preset storage also makes it easy to return to a favourite sound without manually rebuilding the amplifier and effect settings. 24 Built-In Digital Effects The amplifier includes 24 digital effects covering the main categories used in modern guitar rigs. Available processing includes pre-effects, modulation, delay and reverb. Up to five effects can be used simultaneously, allowing a complete virtual signal chain to be stored within each preset. This provides plenty of creative scope for building subtle clean sounds, ambient textures, processed rhythm tones and effect-heavy lead settings. Pre-Effects for Shaping the Guitar Signal Pre-effects are positioned before the selected amplifier model and can influence how the virtual preamp responds. These effects can be used to control dynamics, add additional drive or create more specialised sounds before the signal reaches the amplifier section. This is similar to placing compressor, overdrive, distortion or filter pedals before a conventional guitar amplifier. Modulation, Delay and Reverb The modulation section adds movement and width to clean or driven guitar sounds. Delay can create anything from subtle space to prominent rhythmic repeats, while reverb adds depth and ambience. These effects can be edited and stored independently within each preset. Because they are built into the amplifier, no additional power supplies, patch cables or pedalboard space are required. Bluetooth Audio Streaming A compatible smartphone or tablet can be connected through Bluetooth. Music, backing tracks, online lessons and practice material can then be streamed through the amplifier’s speaker. This makes it easy to play along with songs without connecting a separate audio system. The guitar signal and streamed audio are reproduced together, allowing the relative levels to be balanced from the connected device and amplifier. Marshall Gateway App The Marshall Gateway app provides wireless control over the CODE 25 from a compatible iOS or Android device. The app can be used to: Browse the amplifier’s presets Adjust gain and equalisation Select amplifier models Select power-amplifier models Change virtual speaker cabinets Add and edit effects Save personalised presets Organise a library of sounds Stream music through the amplifier The amplifier remains fully usable from its physical controls when a phone or tablet is not connected. CODE Presets Community The CODE Presets platform allows players to explore sounds created by Marshall and other CODE users. Downloaded presets can provide useful starting points for particular genres, playing techniques or artist-inspired tones. Personal sounds can also be stored and shared with other musicians. This gives the CODE 25 additional creative potential beyond its original factory preset library. Traditional Physical Controls Despite its extensive digital features, the CODE 25 provides familiar Gain, Bass, Middle, Treble, Volume and Master controls. These allow quick adjustments without navigating through the Gateway app. Dedicated buttons also provide access to the different stages of the virtual signal chain. This combination of physical and app-based control makes the amplifier accessible to beginners while still offering detailed editing for more experienced players. Custom 10-Inch Marshall Speaker The CODE 25 is fitted with a custom 10-inch speaker rated at 25 watts. The speaker provides a focused response suitable for home practice and recording while offering greater body than the smaller speakers found in many entry-level amplifiers. Its compact cabinet keeps the amplifier portable and easy to position in a bedroom, teaching room or home studio. Controllable Master Volume The Master Volume adjusts the amplifier’s final output without changing the gain structure and stored level of the selected preset. This allows the same core sound to be used at different listening volumes, making the CODE 25 practical for both quiet home practice and louder informal sessions. Silent Headphone Practice Compatible headphones can be connected through the 3.5mm headphone output. Connecting headphones mutes the internal speaker, allowing presets and effects to be used without disturbing other people. This is especially useful for evening practice and shared living spaces. Wired Auxiliary Input A compatible phone, tablet, computer or audio player can also be connected through the 3.5mm auxiliary input. This provides a wired alternative to Bluetooth for playing songs, backing tracks, lesson audio and metronomes through the amplifier. Why Choose a Digital Modelling Guitar Amplifier? A digital modelling amplifier provides access to numerous amplifier and effect sounds from one compact unit. Traditional guitar amplifiers usually have a particular circuit, gain range and tonal character. A modelling amplifier can recreate several different amplifier styles, making it easier to cover contrasting genres without owning multiple physical amplifiers. Preset storage is particularly useful for learning and recording. Once a tone has been created, the entire sound can be saved and recalled later. This eliminates the need to photograph control settings or rebuild complicated effect chains. Digital modelling also performs consistently at controlled listening levels. The CODE 25 can therefore produce detailed clean, crunch and distorted sounds without requiring the high output levels associated with a traditional valve amplifier. Who Is It For? Beginner Guitarists The factory presets allow new players to access a wide variety of usable tones immediately. As their knowledge develops, they can begin adjusting individual amplifier models, cabinets, effects and EQ settings to understand how each part of a guitar rig influences the final sound. Developing Players The CODE 25 offers significantly more tonal flexibility than a basic two-channel practice amplifier. Its editable presets provide room to experiment with different genres and build personalised sounds as playing ability improves. Home Musicians The compact dimensions, controllable output, Bluetooth streaming and headphone connection make it particularly well suited to bedrooms, flats and home studios. Guitar Students Backing tracks and lesson material can be streamed wirelessly or connected through the auxiliary input. Presets can also be organised around different exercises and musical styles. Songwriters The wide selection of amplifier and effect combinations makes it easy to explore how different tones influence riffs, chord progressions and arrangements. Recording Musicians Preset recall provides a consistent starting point when recording several sections of the same song or returning to an earlier project. The compact combo can also be captured conventionally with a microphone for recording through its custom speaker. Players Exploring Effects The built-in effects provide an accessible way to learn how compression, drive, modulation, delay and reverb interact with different amplifier sounds. Experienced Guitarists More experienced musicians may find the CODE 25 useful as a portable home amplifier, backstage warm-up solution or compact secondary rig. What’s Included?

Creating a Personal Preset Choose a Starting Sound Select one of the 100 existing presets that is reasonably close to the required tone. Starting with a suitable preset can make the editing process quicker and easier. Select the Amplifier Model The amplifier model determines the core gain structure and tonal character. Cleaner models provide greater clarity and dynamic range, while higher-gain models introduce more saturation, compression and sustain. Adjust the Virtual Power Amplifier The power-amplifier model changes the response and feel of the selected preamp. Different selections can make the same basic preamp feel tighter, warmer, more aggressive or more dynamically responsive. Choose a Speaker Cabinet Model The cabinet model affects low-frequency depth, midrange emphasis and high-frequency character. A smaller virtual cabinet may sound more direct and focused, while a larger configuration can add weight and projection. Add Effects Pre-effects can shape the signal before it reaches the amplifier model. Modulation, delay and reverb can then be used to complete the sound. Refine the EQ Bass, Middle and Treble controls allow the preset to be adapted to the guitar, pickups, room and playing style. Balance the Preset Volume Use the preset Volume control to balance the sound against other stored presets. The Master control can then adjust the overall amplifier output. Store the Sound Save the completed settings to the amplifier so they can be recalled during future practice, recording or rehearsal sessions.
