The beauty of an analog circuit is that chaos makes the muse. While you tweak the knob, it affects itself and also other parameters. 

Driven by NUX's white box algorithm (physical modeling) of Neve 1073, Optima Air can replicate the chaos in a compact size, while providing lots of features like USB audio stream, Reverb function, and IR Capture.

Editor Software
You can load 3rd party IRs and edit preset names through editor software.
Optima Air also supports USB audio stream, which means you could use Optima Air as recording interface. You can adjust USB AUDIO routing through editor software. For WINDOWS operating system, please download NUX ASIO Driver from SUPPORT. The editor software offers you built-in LEVEL adjust knob, so you can tweak the 3rd party IR level.

You need to use a condenser microphone for better result. Connect the acoustic guitar to the Optima Air's input, place the microphone and connect to a microphone to a microphone preamp. And connect the microphone preamp's output to the Optima Air's Return (Please check the picture)

Make sure everything's connected, and you are all set to capture.
