Nux Mighty 20BT MKII Guitar Amp

The NUX Mighty 20BT MKII is a compact 20 watt modelling combo that comfortably covers everything from quiet bedroom practice to full band rehearsals and small stages. Packed with powerful amp models, a huge selection of built in effects, Bluetooth connectivity and deep editing via software and app, it is a flexible all in one solution for players who want great tones, easy control and modern connectivity in a grab and go package.

Building on the success of the original Mighty 20 BT, the MKII version refines the sound, feel and feature set. The updated TS/AC HD white box modelling delivers more realistic amp response, while the custom tuned 8 inch G8 20W speaker offers a brighter top end, punchy mids and a thicker low end for a bigger sound than you would expect from such a portable amp. With seven fully programmable channels, integrated Bluetooth audio and MIDI via the included NBT 1 module, and USB connectivity for recording and editing, the Mighty 20BT MKII is designed to slot straight into your daily playing routine.

From Bedroom Practice To The Stage

With 20 watts of power on tap, the Mighty 20BT MKII is equally at home as a low volume practice amp or as a compact live solution. You can dial in inspiring tones at sensible home levels, then take the same sounds straight to rehearsal or a small gig without changing your setup. The amp is designed to transition smoothly between these environments, so you can focus on playing rather than fighting your gear.

Perfect Partner For Your Pedalboard

The Mighty 20BT MKII is an excellent platform for pedal fans. You can bypass the internal amp models and use it as a dedicated power amp, letting your favourite pedals or external modellers provide the core tone. This keeps your sound clear and uncoloured, so your pedalboard remains the star of the show. Whether you prefer classic stompboxes or modern multi effects, the Mighty 20BT MKII gives you the flexibility to integrate them easily.

Advanced Modelling And Effects

At the heart of the Mighty 20BT MKII is NUX's TS/AC HD white box amp modelling and pre effects algorithm. It is designed to react more like a real valve amp, with each control tweak affecting the overall feel and response rather than just switching static sounds. On top of that, you get a vast selection of fully routable effects blocks, including multiple drives, delays, reverbs, EQs, compressors, a noise gate and filter options. This lets you build complete rigs inside the amp, from subtle enhancement to fully produced, stage ready sounds.

Deep Control, Bluetooth And USB

The included NBT 1 Bluetooth module connects via USB C and unlocks Bluetooth audio streaming and MIDI control, so you can play along with tracks and adjust your sounds wirelessly from your phone or tablet. For deeper editing, the Mighty Editor software and MightyAmp app allow you to reorder signal blocks, fine tune every parameter and save your favourite presets. USB connectivity also lets you use the amp as an audio interface, with optional cab simulation for recording direct tones. Plug in headphones and the speaker mutes automatically, giving you a flexible silent practice and recording setup.

• 20 Watt Modelling Combo For Home And Stage - With 20 watts of power, the Mighty 20BT MKII delivers enough volume for rehearsals and smaller gigs while still sounding great at bedroom levels. This makes it a versatile choice if you want one amp to cover practice, recording and live use without changing your core rig.
• TS/AC HD White Box Amp Modelling - NUX's TS/AC HD algorithm is designed to mimic the interactive feel of analogue circuits, so your picking dynamics and control movements translate into a more natural response. This gives you tones that feel closer to a real valve amp, making it easier to dial in inspiring sounds quickly.
• Extensive Built In Effects And 7 Pro Scene Presets - A wide range of drives, delays, reverbs, EQs, compressors, noise gate and filter effects are fully routable inside the amp, letting you create complete signal chains without extra pedals. Seven customisable channels with Pro Scenes allow near seamless preset switching with delay and reverb trails, ideal for polished live performances.
• Bluetooth, App Control And USB Interface - The included NBT 1 Bluetooth module enables wireless audio streaming and MIDI control from your smart device, while the Mighty Editor software and MightyAmp app give you deep editing and preset management. USB connectivity lets you use the amp as an audio interface, with optional cab simulation for recording and automatic speaker muting when using headphones for silent practice.
