NUX Mighty Air is a wireless stereo modelling guitar / bass amplifier with Bluetooth connectivity and a dedicated app that can enhance your tone from your Android and iOS devices. It can serve you for bedroom practice, pre-show warming up, travel entertainment and more. Please download the Mobile App before you play it. Please update the firmware before playing it. For Android Users: Usually, connecting your devices to the Mighty series amplifiers is the same as connecting a Bluetooth speaker. Turn on the Bluetooth, search for the devices, select the amplifier, and it's done. If you are having a connection problem: 1. turn on the "GPS Services" on your device, 2. reopen Mighty Amp app, and 3. allow it to turn Bluetooth on. Now your device is successfully connected, only one step to go: Go to Settings (at the right bottom). Normally you can see your device's name here. If it's not, go to Select Device and choose your amplifier. All set! Now you can activate the MIDI control, tweak the parameters and control your NUX amplifier with your mobile device. Connection the bluetooth by Mobile phone and App for your first playing.
