THE APP FOR STRATUS® & NIMBUS®
Control the most powerful guitar effects pedal and amp modeler on the market, both powered by AI.
AI FX BUILDER — CREATE ANY EFFECT YOU CAN IMAGINE
Just describe the sound you want:
"Give me a dynamic tremolo/phaser that's more tremolo-y and slower when I play softly, but smoothly gets more phaser-y and faster as I dig in."
The AI builds it. Not just a preset... a brand new algorithm. No other guitar gear on earth can do this, and it comes FREE with Stratus and Nimbus.

NEURAL AMP MODELER — 300,000+ AMP & GEAR CAPTURES
In partnership with TONE3000, get instant access to a massive community library of Neural Amp Modeler captures — real tube amps, cabs, and gear, modeled with stunning accuracy. Browse, load, and A/B between model variants right in the app, and share NAM-powered presets with anyone through Chaos Cloud.
Need cabs too? Add Impulse Responses (IRs) as their own effect, also available from TONE3000 for free in the app.

BRING YOUR OWN — UPLOAD YOUR CAPTURES & IRs
Got your own amp captures or impulse responses? Upload your private NAM captures (.nam) and IRs (.wav) straight from the app and drop them onto your board like any other effect. They stay private to your account — your personal tone collection, ready on any device you sign into.

Whether you want classic tube amp tones, ambient soundscapes, or sounds no one's ever heard — Stratus and Nimbus have you covered.
Two devices. One app. Unlimited possibilities. Powered by AI.
*Note: Stratus or Nimbus hardware required
I’ve only left 2 app reviews over the years to the worthiest of developers and this one takes the cake. This is a game changer, period. The quality and sheer variety of tones available through one pedal sized pedal is simply gorgeous. And now with this latest app update, the user experience just caught up with the hardware side of the equation, making this a truly ultimate pairing of hardware and software to create and manage endless possibilities in sought after guitar tone. And the dev team is fantastically available and responsive with a whole community growing - thanks Landon! Every single time I’ve reached out I’ve been not just answered but it’s turned into a thoughtful conversation and I’ve watched in real time as suggestions and feedback get incorporated into the user experience. Hands down one of the best guitar tone experiences available. Get one if you can..

Enjoy ourselves and get the most out of our investment in the stratusphere Good Job Chaos Audio and thank you for the work you’ve done and continue to do!!
a PEDALBOARD in a pedal
SearlesBunch
This is a game changer of an app and hardware pedal. It used to be that you could only have one pedal at-a-time in these kinds of digital recreations of effects, but having an ENTIRE PEDALBOARD at your fingertips is the kind of control we’ve all been waiting for as guitarists. They’re always updating the app in order to make it better and more user friendly. The pedalboard layout is great. The shop is easy to use. Presets are easy to find and save. I really love what they’ve done.
Innovative and exciting

Extremely satisfied overall with this app & product. Standard analog pedalboards will always exist but I think the team at Chaos Audio is truly breaking new ground when it comes to having an all-in-one pedal with dozens of effects that you can set-up and modify pretty easily from your phone. With the new MIDI compatibility update im excited to see the use of it beyond just my practice and in future performances as a standalone option!
