Practice Anywhere, Sound Great Everywhere: The Nu-X Mighty Plug
Whether you're a bedroom guitarist trying not to wake the house, a touring musician warming up backstage, or a bass player without a spare corner for an amp, the Nu-X Mighty Plug might just be the most useful bit of kit you'll buy this year — and it fits in your pocket.
What Is It?
The Mighty Plug is a headphone amplifier that plugs directly into your guitar or bass jack. Connect your headphones, pair your phone via Bluetooth, and you've got a fully-featured practice rig that makes absolutely no noise to anyone else in the room. At just 62g and smaller than a matchbox, it's genuinely pocketable.
Serious Tone in a Tiny Package
Don't let the size fool you. Inside the Mighty Plug is a surprisingly deep arsenal of sounds: 13 amp models, 20 IR cabinet presets, and 19 effect models covering everything from clean headroom to saturated drive. Whether you're dialling in a Fender-style clean or a scooped metal tone, there's plenty to explore.
Bass players are equally well catered for, with dedicated bass amp models that give low-end grunt without the need for a cab.
The Mighty Amp App
Pair the Mighty Plug with your smartphone via Bluetooth and you unlock the free Mighty Amp app (iOS & Android), which gives you full visual control over every amp and effect parameter. It's a genuinely intuitive way to build and save your tones — far easier than scrolling through menus on a tiny device.
Bluetooth also doubles as an audio stream, so you can play backing tracks, Spotify, or YouTube directly into your headphone mix and jam along in real time.
No Batteries, No Fuss
The built-in 1000mAh LiPo battery charges via USB-C, and that same USB-C port doubles as a recording interface — plug straight into your DAW and capture your ideas without any additional hardware. Firmware updates come through the same connection, keeping your Mighty Plug current as Nu-X rolls out improvements.
The Bottom Line
At £55.99, the Nu-X Mighty Plug is exceptional value for what it delivers. It's the kind of tool that removes every excuse not to practice — no amp needed, no noise complaints, no faff. Just plug in and play.
