NUX Stageman II AC-80 | 80W Rechargeable Acoustic Guitar Amplifier
A mobile performance amp for guitar, vocals, rhythm, and looping
The NUX Stageman II AC-80 is an acoustic guitar amplifier from NUX, built with NUX DSP tone processing technology, 80W output, and 2 independent channels. Its acoustic guitar and microphone inputs are optimized separately, while the 6.5-inch woofer and 1-inch tweeter deliver clear, full sound for small stages, busking, and indoor singer-songwriter performances.
Compared with traditional practice amps that offer only a single input, the Stageman II AC-80 integrates a rechargeable amplifier, Bluetooth backing-track playback, drum machine, loop phrase recording, and XLR Direct Out in one combo amp. For solo singer-songwriter performance, recording output, or connection to a PA, it covers the essential performance workflow without requiring a large pile of extra gear.

NUX Stageman II AC-80 Core Technology and Features
-
Dual channels for acoustic guitar and microphone: 2 independent channels are optimized separately for acoustic guitar and microphone input, making it ideal for solo singer-songwriter sets, hosting, and small performances.
-
80W two-way sound architecture: A 6.5-inch woofer and 1-inch tweeter combine with NUX DSP to keep the tone clean and full, with projection that exceeds the cabinet size.
-
Built-in rechargeable battery: Up to about 4.5 hours of unplugged operation, so busking, outdoor, and pop-up performances are not completely limited by outlet location.
-
XLR Direct Out and IR Loader: Send the signal to a recording or PA system through XLR output, while the IR Loader includes 8 preset tones for a more complete direct-recorded sound.
-
Drum machine and loop phrase recording: Built-in rhythm grooves and stacked looping functions let solo performers build rhythm, backing parts, and layers.
-
12 effects assignable to either channel: Chorus, Delay, Tape Echo, Modulation, Reverb, and other effects can be assigned according to performance needs.
-
Bluetooth, app, and dual footswitch control: Play backing tracks or pre-recorded audio, fine-tune controls through the dedicated NUX app, and use dual footswitch operation so your hands can stay on the instrument during performance.
-
Flexible external effects via FX Loop: The built-in FX loop makes it easy to add existing pedals or external signal processing into your performance signal chain.
Stageman II AC-80 Feature Breakdown
Dual-Channel Singer-Songwriter Setup
- The acoustic guitar and microphone each have their own input logic, making the amp suitable for solo singer-songwriter performance, simple duo sets, or hosting small events.
- The two-way speaker design helps separate the guitar's low-mid content from vocal clarity, so the sound does not feel like a thin practice amp.
Recording and PA Output
- The XLR Direct Out can send the amp signal to recording equipment, a mixer, or a live PA, making it useful for performers who need to capture a set or expand venue coverage.
- The IR Loader includes 8 preset tones, helping direct recording or direct output retain a sound closer to a full acoustic cabinet.
Rhythm, Looping, and Effects
- The built-in drum machine and loop phrase recording let you quickly build a rhythmic foundation and layer guitar or vocal phrases.
- The 12 effects include Chorus, Delay, Tape Echo, Modulation, Reverb, and more, and can be applied to either channel for a more complete performance sound.
Mobile Performance Control
- The built-in rechargeable battery provides up to about 4.5 hours of unplugged performance. With Bluetooth playback for backing tracks or pre-recorded audio, it makes busking and outdoor setup fast.
- The dedicated NUX app enables more detailed control, while hands-free dual footswitch operation suits users who need to switch functions while performing.
