Being a musician today requires too much gear. Pedals, amps, loopers, audio interfaces, mixers, and power supplies all add up to a complicated, expensive, and bulky setup.

Practice at home? You need Bluetooth speakers or an aux-in amp.
Recording? You need an interface, cables, and software.
Gigging? You’re dragging amps, pedals, and more gear than you’d like.

Competitors like Spark, Katana, and Mustang tried to simplify things, but they lock you into factory sounds and closed systems that can’t evolve with you.

In some cases, like Lava Studio, they charge you twice as much for basic features like a single quarter-inch input and limited power.

Nimbus is a music studio in a box. It’s your amp, interface, speaker, interface, looper, pedalboard, cabinet, mixer, and more.

A powerful 70W stereo amp.
Two combo XLR + quarter inch instrument inputs.
A USB audio interface for your DAW.
A looper for building songs live.
Stereo Bluetooth audio streaming.
Dual quarter-inch line-outs for larger gigs.
Full MIDI support for live control.
A full plugin host with Chaos Audio, 3rd party, and even user-made effects.
1/4″-20 threaded hole on the bottom for mounting onto speaker stands.
And it all fits into a lightweight amp you can carry with one hand.

Inside Nimbus is a 1GHz ARM Cortex processor running on a real-time Linux OS.

5x more powerful than Spark’s DSP chip.
Handles multiple effects and amp models at once.
Sub-3ms latency means no noticeable delay when playing.
64GB storage for amp models, IRs, and plugin data.

Nimbus is the first instrument amp built with the power of a computer inside.

We partnered with PowerBass, a respected speaker manufacturer, to equip Nimbus with dual 4″ S-4002 speakers and dedicated tweeters.

70W RMS stereo output (105W peak).
20Hz–20kHz frequency range for full clarity.
Louder, cleaner, and more balanced than Spark, Katana, or Mustang.

The result? Nimbus sounds like a premium studio monitor system built directly into your amp.

Nimbus comes alive when paired with the Chaos Audio mobile app. Whether you’re dialing in tones at home or tweaking presets on stage, the app makes it fast and intuitive.

Fully customizable pedalboard: Build your signal chain in seconds. Add, remove, or reorder effects as if you’re wiring a real board.
Tone Shop integration: Download new Chaos Audio, third-party, and user-created plugins directly from the in-app marketplace.
Cross-device sync: Any plugin you buy works instantly on Nimbus, Stratus, and your desktop DAW.
Preset management: Save, name, and organize your favorite tones. Assign them to footswitches or MIDI controllers.
Bluetooth control: Adjust settings wirelessly while sitting across the room, no cables required.

Closed systems limit creativity. Nimbus is open by design.

Chaos Audio plugins included at launch.
3rd party plugins from developers like ChowDSP, Shnobel Tone, and Manic FX.
User-contributed plugins you can create yourself with FAUST or C++.
Impulse Response loading: Store up to 10 IRs (256, 512, or 1024 sample lengths).
Neural amp model support: Load your own AIDA-X captures. NAM compatibility is in the works.

Nimbus doesn’t just keep up with the future, it lets the community shape it.

Nimbus is equipped with more I/O than any competitor.

2 x XLR + 1/4” combo inputs (mic + guitar simultaneously).
2 x TS line outs (L/R or dual mono).
Headphone out (stereo) + AUX in (stereo).
USB-C 2-in/2-out audio interface for Mac & PC.
USB-A for MIDI controllers or device charging.
Second USB-C port for software updates.
Bluetooth 5.0 audio streaming + BLE control.
Wi-Fi, included and unlocked post-launch via OTA.

Nimbus balances hands-on control with full app integration.

Multiknob for fast scrolling and adjustments.
7 RGB LEDs to indicate presets and signal status.
Mobile app (Bluetooth) for full control of effects chains.
Web app (nimbus.local) for desktop editing.
MIDI input support for live switching and looping.
Built-in 5-minute looper for practice and songwriting.

Nimbus is the only smart amp with built-in, open-source machine learning amp modeling.

Use AIDA-X, a free AI amp model loader, to capture real amps and play them inside Nimbus.
Save your own tones or download others shared by the community.
NAM support (Neural Amp Modeler) is being looked into for even more compatibility.

Out of the box, Nimbus will come loaded with a full suite of Chaos Audio effects and amps at no extra cost:

20+ distortions, delays, reverbs, modulation, compressors, EQs.
25+ Chaos Audio amp models with matching cabinet sims.
45+ free effects and amps to cover every genre and style.

Practice: Stream backing tracks via Bluetooth, loop, jam, and experiment.
Perform: Mic + guitar simultaneously, controlled by MIDI footswitches.
Record: Use Nimbus as a 2-in/2-out USB-C audio interface with zero extra gear.
Experiment: Load new plugins, IRs, and amp models.
