NUX NAI-5 Optima Air｜Call Simulator and Preamplifier｜Acoustic Simulator & IR Loader

Optima Air is a box guitar sound simulation effects pedal developed for acoustic guitar and equipped with a preamplifier.

After the sound of the guitar is picked up by a magnetic or piezoelectric pickup, the signal enters the OPTIMA AIR.
You can use our pre-set models to change the guitar's tone to classic acoustic guitars such as Martin, Taylor, Gibson, etc.

You can also use your electric guitar to simulate the sound of these acoustic guitars through OPTIMA AIR!

It also has a cabinet sampling function inside!
If you have an acoustic guitar, he can also record it for you.
When you're out and about performing, you can use your electric guitar to simulate the tone of your acoustic guitar without having to bring multiple guitars!

Features

• IR function
  Optima Air contains 15 IR files.
  Each IR file contains the guitar type and pickup type.
  The IR file name includes guitar profile, optimized guitar type, and pickup type. Press the IR footswitch to turn on/off the IR function.
  
• Air preamplifier
  The Optima Air features a preamplifier with gain and three-band EQ.
  Its subtlety lies in the fact that we used NUX's latest TS/AC-HD physical modeling algorithm to simulate the EQ circuit of the classic Neve 1073 microphone amplifier.
  The classic saying of analog circuits is that when you adjust a parameter, the overall tone will change slightly. NUX's TS/AC-HD algorithm restores this feature by modeling the original circuit, allowing you to have the same charming tone in the recording studio on site.
