NUX Mighty Lite BT MKII Desktop Modeling Amplifier

Introduction

Thank you for purchasing the NUX Mighty Lite BT MKII. Since launching the Mighty Lite BT in 2018, NUX has been hard at work incorporating the latest innovations in amp modeling into this brand new version. We hope you enjoy using it.

The Mighty Lite BT MKII provides a variety of effects for electric guitar and bass guitar including amp modeling and cabinet IRs. It also comes with acoustic amp modeling and acoustic IRs to let you simulate acoustic guitar tones. You can also load 3rd party IRs through the Mighty Editor™™ edit software to expand your tone. (You can load any WAV format IRs; the Mighty Editor™™ will convert them to 32bits/48kHz automatically.)

You can customize the presets through the MightyAmp™™ APP (mobile) or Mighty Editor™™ edit software (PC). You can do lots of things with the intuitive interface, experience it, feel the versatility and mighty!

Note: There are 36 default IRs, and user IR slots are 18 (from 37 to 54).

The MightyAmp™™ APP and Mighty Editor™™ edit software allow you to tweak all the signal blocks and parameters. The Mighty Lite BT MKII includes GATE, EFX, AMP, IR, MOD, DLY, and RVB signal blocks. Along with the included 36 built-in IRs, there are 18 empty slots for 3rd party IRs loading. No need to worry about the sampling rate; Mighty Editor™™ edit software can convert the WAV(IR) format automatically.

Control Panel

The MIGHTY LITE BT MKII supports USB-C audio stream, which means that it can be a USB recording interface. It supports Normal / Dry Out / Re-amp / Loopback routing, which you can adjust through the MightyAmp™™ APP or Mighty Editor™™ edit software. No need to set up USB OUT in DAW. Even live stream jamming with Loopback!
