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. ## Frequently Bought Together - NUX Optima Air Dual-Switch Acoustic Guitar Simulator with a Preamp,IR Loader, Capturing Mode - D'Addario Accessories Guitar Pedal Power Supply - DC 9V Power Cord - 9V Power Supply for Guitar Pedals - Pedalboard Power Supply - PW-CT-9V - MXR Patch Cable 6 in|15 cm - 3 Pack (3PDCP06) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sg/products/658057870-optima-air-dual-switch-acoustic-guitar-simulator-with-preamp-infrared](https://www.desertcart.sg/products/658057870-optima-air-dual-switch-acoustic-guitar-simulator-with-preamp-infrared) --- *Product available on Desertcart Singapore* *Store origin: SG* *Last updated: 2026-10-22*
