The NUX NAI-5 Optima Air pedal is a dual-switch acoustic guitar simulator with a preamp for both acoustic and electric guitar players. It simulates the acoustic guitar profiles with the best-optimized sound depending on your guitar and pickup type.
The IR section gives you 15 built-in acoustic guitar profiles, and it also support 3rd party IRs. The preamp section is modeled after the famous Neve 1073 by using a white-box algorithm. It is equipped with a 3-band EQ and Gain controls, plus there is an additional one-knob-control Reverb effect. You can connect other effect pedals to the built-in SEND/RETURN effect loop and use the XLR jack on the Optima Air as D.I. Out. There is also a headphones output for silent play and an auxiliary input to connect a music player to play along.
NUX Optima Air has a unique profile capture function, so you can create your own acoustic guitar profile (IR file) by directly capturing your favorite acoustic guitar's sound.
If you are a gigging guitarist or home recording musician, you will find the NUX Optima Air very convenient, because you won’t be obligated to have to haul around and keep track of a bunch of different guitars. As a bonus, the Optima Air also works as a USB Audio interface!
