Chaos Audio: Effects & Amp AI

Plug in, dream up a sound, and hear it come to life. Chaos Audio is the multi-effects pedal and amp modeler companion app for the STRATUS multi-effects pedal and NIMBUS modeling amp - powered by AI, neural amp modeling, and a massive cloud of effects.

Requires a STRATUS pedal or NIMBUS amp to use (companion app).

DESCRIBE IT. PLAY IT.
Type what you want to hear and the AI FX Builder generates a brand-new effect algorithm - not a preset, an actual new effect. It is a genuinely new way to create custom guitar effects and discover tones you would never dial in by hand. If you can describe it, you can play it.

NEURAL AMP MODELER (NAM) + IMPULSE RESPONSES
Tap into the Neural Amp Modeler and 300,000+ amp and gear captures through our TONE3000 partnership.
- Browse, load, and A/B between model variants on the fly
- Chase classic tube amp tones, boutique rigs, and rare gear
- Share NAM-powered presets with friends via Chaos Cloud
Add TONE3000 impulse responses (IR) as a simple two-knob effect with Mix and Output controls. Multi-IR packs include a variant dropdown, and a built-in CPU meter shows your headroom. Great for cabinet impulse responses and amp sims; very long reverb-style IRs are shortened to a fixed length.

USE YOUR OWN CAPTURES
Upload your own private NAM captures (.nam) and impulse responses (.wav) right from the app. They stay private to your account and sync to any device you sign into.

A WORLD OF EFFECTS
Explore the open Tone Shop marketplace and download effects from top third-party brands. Your tone, your way.

BUILD YOUR PEDALBOARD
- Chain up to 7 effects in any order on Stratus
- Drag and drop to reorder your signal path instantly
- Unlimited presets: save, load, and share (NAM included) with friends

NEVER LOSE A TONE
Presets auto-back-up to your Chaos Audio account and restore on a new device or reinstall. Your sound follows you everywhere.

EVERYTHING YOU NEED TO PLAY
- Live chromatic guitar tuner to stay in tune fast
- 5-minute looper to record, layer, and loop hands-free
- Hands-free preset switching with Preset Control or MIDI
- Optimized for Android phones and tablets, with two-column landscape layouts on bigger screens

MEET NIMBUS
NIMBUS brings world-class modeling to a portable amp with built-in speakers and dual inputs - plug in guitar, bass, vocals, or any instrument. It uses the same Tone Shop library as Stratus, so you can practice, record, and perform anywhere.

HIGHLIGHTS
- AI that builds effects from your words
- A near-endless library of amp models, IRs, and effects
- Cloud backup so your tones are always safe
- One app for both Stratus and Nimbus

Whether you want an AI guitar effects generator, a neural amp modeler, an amp simulator, an IR loader, a looper, a chromatic tuner, or a full guitar pedalboard app, Chaos Audio brings your STRATUS pedal and NIMBUS amp to life.

Note: Chaos Audio is a companion app and requires a STRATUS pedal or NIMBUS amp to function. Plug in. Describe your sound. Play it.
