Bring a versatile range of professional tones to your playing with the M-VAVE MK-20, a compact guitar and bass multi-effects floor processor powered by ANN (Audio Neural Net) modelling technology. Combining amp modelling, cabinet simulation, an extensive effects library, a built-in expression pedal and wireless connectivity, the MK-20 offers a flexible solution for practice, live performance, home recording and studio production.

With 120 preamp models and over 320 effect types across 10 editable effect modules, the MK-20 covers a wide range of sounds for electric guitar, bass and acoustic guitar. Its ANN modelling technology is designed to recreate the response and feel of traditional tube amplifiers, while 100 cabinet models and support for third-party impulse responses provide additional options for shaping your tone. The fully customisable signal chain allows the order of the effect modules to be tailored to different sounds and playing styles.

Flexible Tone Creation

The MK-20 provides an extensive selection of effects for shaping everything from clean, articulate tones and classic overdrive to high-gain distortion, spacious reverbs and rhythmic delays. Its modulation effects add movement and texture, while global EQ offers tonal adjustments to suit different instruments and audio setups.

The 2.4-inch LCD screen presents preset and effect information in a clear format. Customisable footswitch functions, preset-list mode and six dedicated snapshot slots provide further flexibility for organising sounds and adapting settings to different performance requirements.

Recording, Connectivity & Software

USB-C connectivity enables computer audio, MIDI communication, compatible software interaction, firmware updates and supported tone-file transfers. Re-amping support adds flexibility to recording workflows by allowing previously recorded dry instrument tracks to be processed through the MK-20. OTG recording support also makes the processor suitable for compatible mobile recording setups.

Bluetooth audio supports wireless music playback, while BLE MIDI and compatible mobile applications provide additional connectivity options. Free companion software for Windows, macOS, iOS and Android supports tone management, preset sharing and compatible third-party amp and cabinet file imports.

Finished in black, the M-VAVE MK-20 combines a broad tonal palette, integrated performance tools and modern recording features in one compact floor processor.
