Nimbus specifications updated September 10, 2026. Nimbus is currently available for preorder. See the current product page for specifications, pricing and the latest delivery estimate.
Every great product has an origin story. For Nimbus, that story begins with a compact multi-effects pedal called Stratus. Understanding where we came from helps explain where we're going, and why Nimbus represents such a significant leap forward in what a guitar amp can be.
The Birth of Stratus: Solving Real Problems
When we launched Stratus, we had a simple goal: create an affordable, compact multi-effects pedal that didn't compromise on quality or versatility. Guitarists were tired of lugging around massive pedalboards to gigs. They wanted something that could fit on a small corner of their setup while still delivering everything from pristine cleans to crushing distortion.
Stratus delivered exactly that. At just $199, it packed a 5-minute looper, hands-free preset switching, and the ability to chain up to seven effects simultaneously. We included over $260 worth of meticulously crafted effects right out of the box, from the Transit digital delay to the Starlight shimmer reverb.
But the real innovation wasn't just the hardware. It was what came next.
Tone Shop: The Open Platform Philosophy
Early on, we made a decision that would define everything Chaos Audio builds: we believed guitar gear should be open, expandable, and constantly evolving. This led to the creation of Tone Shop, our online effects marketplace.
Tone Shop helped create an ecosystem where developers could create and share their own plugins, where the community could influence what gets built next, and where new capabilities could arrive through software updates.
The shared platform allows effects and software capabilities to develop after hardware is released. Current Nimbus specifications now use native NAM playback; earlier descriptions of its AIDA-X implementation no longer describe the current design.
Lessons Learned: What Guitarists Really Need
Building Stratus and running Tone Shop taught us invaluable lessons about what guitarists actually need versus what they think they need.
Lesson 1: Simplicity wins. Despite having deep editing capabilities, most users gravitate toward presets and quick adjustments. They want to sound great now, not spend hours tweaking parameters. This informed Nimbus's approach to preset management and its intuitive mobile app.
Lesson 2: Connectivity matters more than features. Bluetooth control in Stratus was initially seen as a nice-to-have. It quickly became the most beloved feature. Guitarists wanted to adjust their sound without bending down mid-rehearsal. They wanted to browse effects while sitting on their couch. This wireless-first approach became central to Nimbus's design.
Lesson 3: Recording integration is essential. We noticed a pattern in support tickets and community discussions: guitarists increasingly needed to record at home. They were buying separate audio interfaces, dealing with latency issues, and struggling to capture their Stratus tones directly. This directly inspired Nimbus's built-in USB audio interface.
Lesson 4: Power and portability aren't mutually exclusive. Stratus proved that a compact device could deliver serious tones. But for practice and small venues, guitarists still needed an amp. Why couldn't the effects unit and the amp be the same device?
From Pedal to Platform: The Nimbus Vision
Nimbus isn't just a bigger Stratus with a speaker. It's a complete reimagining of what a practice amp can be when you apply everything we learned.
100W stereo amplification and custom PowerBass collaboration speakers angled at 15° bring playback into the same device as the effects. Actual room coverage depends on placement, listening distance and the rest of the band.
A USB-C audio interface gives Nimbus a direct recording connection to a computer. Check the current setup instructions for your computer, DAW and monitoring needs.
Two combo inputs support both XLR microphones and guitar, making Nimbus a complete solution for singer-songwriters and content creators.
The same open platform that powers Stratus now powers Nimbus. Every effect in Tone Shop works on both devices. Your presets sync across both. The community you've been part of continues growing.
The Technology Under the Hood
Current Nimbus specifications include 16GB onboard storage and support for a compatible NAM model alongside effects and cabinet IR processing.
Nimbus now runs NAM natively in A2-Lite mode without format conversion. It supports one NAM model at a time, combined with effects and IRs. AI FX Builder provides another path to sound creation: describe an effect, generate it in the cloud and run it locally on the amp.
The result is a smart amp that sounds remarkably analog while offering digital convenience and expandability.
Preserving What Works
Despite all the new capabilities, we were careful not to lose what made Stratus special:
- Affordability: Nimbus offers premium features at a fraction of what competitors charge for similar capabilities.
- The mobile app: The same friendly, intuitive app that controls Stratus also controls Nimbus. Existing users feel immediately at home.
- Tone Shop integration: Your existing effects library carries over. No starting from scratch.
- Software updates: Nimbus will continue to gain new features and capabilities over time, just like Stratus has.
Two Products, One Philosophy
Stratus isn’t going anywhere. For guitarists who already have an amp they love, it remains a compact effects solution with 19 free effects covering all effect categories, 30 free AI builds every month in FX Builder 2.0, and access to all 600,000+ amp and pedal NAM captures on TONE3000.
Nimbus serves guitarists who want an all-in-one solution: amp, effects, recording interface, and Bluetooth connectivity in a single, portable package. It's for the bedroom guitarist who occasionally plays small gigs, the content creator who needs great tones without a complex setup, and the traveling musician who can't bring their full rig everywhere.
What's Next
The journey from Stratus to Nimbus reflects the value of an expandable effects platform. For current features and release information, use the product pages and help center rather than relying on early development announcements.
Both Stratus and Nimbus will continue to improve over time. That's the beauty of an open platform: your gear gets better the longer you own it.
If you've been part of the Stratus community, thank you for helping us build something better. If you're discovering Chaos Audio through Nimbus, welcome to a different way of thinking about guitar gear.
The future of guitar isn't about choosing between analog warmth and digital convenience. It's about having both, in your hands, constantly evolving.
