NUX Optima Air Acoustic Preamp / IR Loader Test By Jimmy Lin (No Talking)

New acoustic preamp pedal for NUX. This is by far the most powerful one I've ever used! Not only it's a great sounding pedal, but also full of interesting functions. The most exciting one must be the tone capture function! Means that you can simulate any acoustic guitar tone, and make it into an IR file. Call it out anytime you want as a preset! How awesome is that! Wait, there's more~ The NUX Optima Air also can be an IR loader pedal! You can put in 8 third party IR files using the editing software. This
