The NUX PA-2 is a guitar modeling preamp made by NUX, a compact unit aimed at players who want preset-based amp voicings plus practice tools in one box. It carries 18 preset types, a built-in tuner and metronome, and an AUX input for playing along with external music. It sits in the same family of acoustic and preamp tools as the NUX Stageman Floor.1
What it does
The PA-2 is a modeling preamp: it shapes your guitar signal through preset voicings rather than a single fixed tone. It offers three modulation types, listed as Plat, Jumbo and Moelleux (roughly flat, jumbo and mellow), giving you three broad voicing characters to work from.1
The preset system splits into two banks:
- P1-P9: factory presets, ready to use out of the box
- U1-U9: user slots you configure to your own needs1
Tuner, metronome and practice features
Beyond preamp duties, the PA-2 doubles as a practice tool. It has a built-in metronome with selectable rhythm patterns, useful for timing practice without a separate device. The tuner offers two modes, Chromatic and Guitar, plus a flat tuning function for players who tune down.1
The AUX-IN jack lets you connect external music players such as mp3 and CD players, so you can play along with backing tracks or songs directly through the unit.1
Power and availability
The PA-2 runs on a 9 V DC supply rated at 200 mA or more, and the supply is not included.1
No retailer currently offers the NUX PA-2 and no classified ads exist for it, so it appears to be discontinued or otherwise off the market.1

Questions
Is the NUX PA-2 still available?

Can I play along with an mp3 player through the NUX PA-2?
Yes. The PA-2 has an AUX-IN jack for connecting external music players such as mp3 and CD players, so you can plug in a playback device and practice along with your own tracks.
How many presets does the NUX PA-2 hold?
It holds 18 preset types: P1 through P9 are factory presets, and U1 through U9 are user slots you can configure to your own needs. That gives you nine starting points plus nine of your own sounds.

It runs on a 9 V DC power supply rated at 200 mA or more, which is not included with the unit. A standard 9 V pedal power supply meeting that current rating will work.
