NUX Mighty 20 MKII 20W Modelling Guitar Amplifier
The NUX Mighty 20 MKII is a versatile 20-watt modelling guitar amplifier designed to deliver serious tones for home practice, rehearsals, recording and live performance. Building on the popular Mighty 20 BT, the MKII takes things further with NUX's TS/AC-HD White-Box modelling technology, a powerful collection of effects, seven programmable presets with Pro Scenes, Bluetooth connectivity and USB audio functionality.
Whether you're just starting out, experimenting with different sounds or building a pedalboard, the Mighty 20 MKII gives you an impressive range of tones in a compact and practical amplifier.
Authentic Amp Modelling & Responsive Tone
At the heart of the Mighty 20 MKII is NUX's TS/AC-HD White-Box Amp Modelling algorithm, designed to provide a more natural and responsive playing experience. Rather than simply switching between static digital sounds, the system is designed to respond dynamically to the way you play and adjust the controls.
The result is a highly playable amplifier that can cover everything from clean and dynamic tones through to overdriven and high-gain sounds.
A Huge Range of Built-In Effects
The Mighty 20 MKII gives you plenty of creative options without needing a pedalboard full of individual effects. Its effects system includes:
- 13 dirt/distortion effects
- 5 delay variations
- 5 reverb variations
- 2 EQs
- 3 compressors
- Noise Gate
- Filter
- Modulation effects
- Flexible effect block routing
The signal blocks can be reordered, allowing you to customise your signal chain and create your own combinations of amp and effects.
7 Presets with Pro Scenes
The Mighty 20 MKII features 7 fully customisable presets, giving you quick access to your favourite sounds.
Its Pro Scenes function takes this a step further by allowing you to switch between different amp and effect configurations with minimal interruption. Delay and reverb trails can continue naturally when changing presets, making the system particularly useful for live playing.
Excellent Pedal Platform
Already have a collection of guitar pedals or a modern multi-effects/modeling unit? The Mighty 20 MKII is designed to work with them.
The amp can bypass its internal amp modelling, allowing it to function as a practical power amp platform for external pedals and modelers. This gives guitarists the flexibility to use the Mighty 20 MKII as the centre of a traditional pedalboard setup or alongside more advanced digital gear.
Custom-Tuned 8-Inch Speaker
NUX has fitted the Mighty 20 MKII with a custom-tuned 8-inch G8-20W speaker. Rated at 20 watts with a 4-ohm impedance, the speaker is designed to provide a bright character, balanced mids and a strong, thick low end.
The combination of modelling technology and a dedicated guitar speaker gives the Mighty 20 MKII a lively and responsive feel that works well across a wide range of playing styles.
Bluetooth Audio & MIDI
The included NUX NBT-1 Bluetooth Module adds wireless connectivity to the amplifier.
Connect your smartphone or tablet for Bluetooth audio streaming, making it easy to play along with backing tracks, lessons or your favourite songs. Bluetooth MIDI also allows compatible devices to control and edit the amplifier.
MightyAmp App & Mighty Editor
For deeper control over your sounds, the Mighty 20 MKII works with the MightyAmp App for iOS and Android, as well as Mighty Editor software for computers.
You can edit tones, customise presets, rearrange signal blocks and save your favourite sounds, giving you much more control than the front-panel controls alone.
USB Audio & Recording
The Mighty 20 MKII can also function as a USB audio interface, making it useful for home recording and computer-based music production.
Connect the amplifier to your computer via USB to access audio streaming and editing functions. With the appropriate cab simulation settings enabled, you can record your guitar directly into your computer without needing a separate audio interface.
For silent practice, headphones can be connected while the amplifier's speaker is automatically muted.
Built-In Looper & Drum Machine
Need to practise your rhythm playing or work on ideas? The Mighty 20 MKII includes a 30-second phrase looper with automatic tempo detection and a built-in drum machine.
It's a great way to practise lead lines, chord progressions, solos and songwriting ideas without needing additional equipment.
