Nux NAI5 Optima Air Acoustic Guitar Preamp/DI with IR Loader

The Nux Optima Air is a dual-switch acoustic guitar simulator with a preamp for acoustic and electric guitars. It simulates any acoustic guitar tone, and converts it into an IR file with the best-optimized sound, depending on your guitar and pickup type.

NUX Optima Air has a unique profile capture function, so you can create your own acoustic guitar profile (IR file) by capturing your favorite acoustic guitar's sound. The IR loader is combined with a pre-amp that allows you to fine-tune your sound with a 3-band equalizer. There’s also an extra one-knob-control Reverb Effect. Attach any effect pedal using the SEND/RETURN effect loop, and add the Optima Air into the signal chain.

There is an XLR DI output for direct line/mixer connection, headphones output for silent play, and auxiliary input to connect and play along to a music player.
