Each impulse response file optimized for the guitar type and the pickup type. The IR file names are included the guitar profile, optimized guitar type, and the pickup type. Press the IR footswitch to activate/deactivate the IR function. NUX Optima Air is equipped with a pre-amp that allows you to enhance your sound by using a 3-band equalizer. 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. Capturing a Guitar Profile Run the pedal in capturing mode; press the IR footswitch and hold, plug in the power cable. 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 Make sure everything's connected, and you are all set to capture. Specifications

Review: Sounds great if you make your own profiles - I have not experience any of the issues with noise that other reviews mention, maybe there are quality control issues with these that I haven't experienced? Turning the IR mix up too far definitely introduces some noise, more for some profiles than others, so maybe keep that in mind. I've been using this for over a year for playing mandolin live with a loud five-piece acoustic combo and have no complaints. I started by using one of the piezo pickup profiles that was built into the pedal and it immediately sounded better than any other preamp pedal I had ever used with mandolin. I previously used an LR Baggs para eq DI box and a BBE Acoustimax and both were ok because they allowed me to tweak the eq myself rather than depending on my sound guy to get it right, but they were definitely both lacking. I scheduled an hour in the studio my band records in because they have a great mic locker -- I generally record my mandolin with a really nice vintage Neumann U67 so we created a profile with that and a few other mics. We just ran the mic through the board for its preamp and back into the mic input for the pedal and then ran the pickup output into the other input (the manual explains how to do this). For run, we ran this with the U67, an AKG 414, a small diaphragm condenser (don't recall what) and, for fun, an SM57. The U67 and 414 both produced great profiles that were noticeably better than any of the built in profiles. We did some experimenting after the fact since everything was hooked into the board, so we did some simultaneous recording direct from the pickup with the model as well as with the microphone the profile was made with so we could really compare how it sounded and everyone in the studio was really impressed. I should mention that we did this with my Northfield F5 with a K&K pickup installed. I also have a Rigel and plugging that in with the profile for my Northfield was sub-optimal. So I'm pretty sure the key to really getting value out of this pedal is getting access to a few really nice mics and making your own profile. So maybe find a studio with a good collection of mics and book an hour or two to make some profiles for your instruments. One other feature that I've found useful is the ability to switch profiles with the buttons. In addition to overall challenges with reproducing the sound of mandolin accurately with pickups, the instrument also has a rather large dynamic range, especially when you compare the volume of playing chords to the volume of playing single notes. I set up my pedal with two copies of the same profile next to each other but one of the presets has the volume slightly boosted, so I can switch back and forth when I take a solo. I'm still getting used to this but I find it sounds better than the boost pedal I had been using. I don't have any experience with any of the other IR pedals, so I can't compare, but this seems to be the cheapest option in the market and I'm very happy with the results.
Review: Not what I hoped for... - I had so many plans for this little gem. The sound was awesome, it did just what I wanted. That is, for about 3 or 4 Sundays at church... then it started making weird white noises. One time it sounded like a jet was slowly coming towards us then just got louder and louder and louder. Power cycling resolves the issues but you can't power cycle the pedal without it popping in the mains, kinda not what you want during church service. The problem and reason for the 1 star is I contacted NUX support which they responded asking for additional information. Then they wanted me to video the problem. Well I thought I may be able to but after a few months, I decided it was just not possible. I did give additional info such as it seemed the white noise is in the amp side of the pedal. I got no response. I recently (6 weeks or so) replied again saying they needed to decide how they would resolve this issue before my warranty ran out. Again I got no response. They have no intention replacing or fixing they problem. Their last response said they recommend I don't use the pedal for more than an hour but our church services can be 2-3 hours plus sound check and set run thru before church starts. That can be from 8am till 1230p. If you only plan to use it 30-45 mins, it does a good job. But if you're planning to gig with it, move on... its not worth the headache. God bless yall

## Questions & Answers

**Q: Why does this pedal have to be unplugged and plugged back in to power supply for it to power up?**
A: I had to check. There’s no on/off switch. It’s not an issue for me since it’s part of a pedal board that I move to gigs. If you’re not moving it there would not be a problem leaving it plugged in and powered up all the time - unless you get hit with a power surge.

**Q: Any update on the noise/static issue that many reviewers have with this pedal? Is NUX actively working on a solution?**
A: Hi!  I've read reviews over a year old that warn of this same problem.  Because I had the problem a couple months ago, I'm inclined to think NUX has not made it a priority to fix.  Not sure, but that's how it appears.

I bought a 2nd NUX Optima pedal that I left plugged in and on at home, and after enough hours, it exhibited the same noise problem.  As with the first Optima Air (which I returned,) the noise, once it starts can be affected by turning the treble control.  Turning the treble pot changed the quality of the crackle and would make a BOOM sound at a certain point in the pot's sweep.  This was true of both my first Optima Air, and also the second one I bought (both new...)

Once it started making its noise, I worked the treble pot back and forth many many times.  After a while, the crackling and BOOM settled down, got quieter with each pass, and then stopped.  This is the sort of operation you might try with a very old pot...maybe with some contact cleaner.  Impurity on the manufacturing process? Dust?  Who knows, but I was able to get the noise to lesson and then go away entirely by working the treble pot back and forth, over and over...until whatever noise-encouragin impurity was finally worked away.

Since then, I've used the pedal with NO ISSUES.  It has worked fine for me for many gigs.

NUX ought to be ashamed, or, barring that (or fixing it), at very least include this solution in their troubleshooting/solutions.  The clarity/thoroughness of their documentation is content for a whole other review...

Hope this helps!

**Q: Can i use a standard boss power supply with the nux optima air ?**
A: I don't know, I bought the NUX ACD-006A for my Optima. It's a low-noise 9v DC 500mA, center = negative, outer shell = positive.

**Q: Will this work with a acoustic guitar that has a transducer?**
A: Yeah, it will work with soundboard transducers or under saddle transducers.

### ⭐⭐⭐⭐ Great if you only use the IR switch
*by S***R on June 9, 2022*

Update (July 2022): finally got my hands on an AudioSprockets Tonedexter and this pedal can’t really compete. My advice is to save your money and buy the Tonedexter. Several people have commented that this pedal generates noise when plugged in for awhile. It may never happen to you, but it happened to me during a gig. So I got the genuine NUX power supply. And again during a rehearsal it started distorting on me. So why am I giving it four stars? Because the distortion only happens when the AMP section of the pedal is engaged. If you just need a cheap way to record an impulse response of your instrument this pedal is great. I only use it with the IR switch engaged, because the AMP switch seems unreliable. If you already have an EQ pedal, put that in the effects loop and don’t use the built-in equalizer. Or put this pedal in the effects loop of a Baggs Para DI or vice versa. Sure, the Optima Air adds a bit of hiss to the signal when it adds high frequency information to match a mic, but the LR Baggs Voiceprint DI adds nearly as much noise. I’m currently using the Optima Air on my violin with a Schertler pickup that I trained to sound like a DPA mic. I wanted an Audiosprockets ToneDexter, but there’s no ETA on when those will be back in stock. Take your time capturing profiles. If you’re close-micing, you really should eq the mic to reduce proximity effect before the signal goes into the pedal or you’re going to encounter feedback in a live environment.
