Choosing between multi-effects pedals can be tough, especially when both options bring something unique to the table. In this comparison, we'll break down the Chaos Audio Stratus® and the Line 6 HX Stomp—two compact multi-effects units that take very different approaches to guitar effects processing.
At a Glance: Stratus® vs HX Stomp

| App Control | Yes (Bluetooth) | Yes (HX Edit, USB only) |
| Looper | Built-in | Built-in (shorter time) |
| MIDI | USB MIDI (via Knot host) | MIDI In/Out built-in |

| Open Platform | Yes – 3rd party plugins | No – closed system |
| Wireless Control | Bluetooth | No |
| Plugin Marketplace | Tone Shop™ | None |
Sound Quality
Both pedals deliver professional-quality tone. The HX Stomp benefits from Line 6's decades of amp modeling expertise—the Helix engine is widely regarded as one of the best digital amp modelers available. If amp modeling is your primary focus, the HX Stomp has a larger built-in library.
The Stratus® takes a different approach. Rather than packing in hundreds of built-in models, it focuses on high-quality individual effects—overdrives, delays, reverbs, fuzz, modulation—each modeled after specific classic pedals. Many Stratus effects are modeled after legendary circuits (Klon Centaur, Tube Screamer, Memory Man, etc.) with attention to authentic feel and response.
Verdict: HX Stomp wins on built-in amp modeling variety. Stratus wins on effects authenticity and the ability to keep growing through downloads.
Expandability and Future-Proofing
This is where the two pedals diverge most dramatically.
The HX Stomp is a closed system. What ships on the unit is what you get (plus occasional firmware updates from Line 6). There's no third-party plugin support, no user-created effects, and no marketplace.
The Stratus® is built on an open platform. The Tone Shop™ marketplace lets you browse and download new effects—from Chaos Audio, third-party developers like ChowDSP, and even user-created plugins. Your pedal literally gets better over time as new effects are released.
For guitarists who value customization and longevity, this is a significant advantage. Your Stratus® today won't sound the same as your Stratus® a year from now—it'll have more effects, more options, and more capabilities.
Verdict: Stratus wins on expandability. If you want a pedal that evolves, this is it.
User Experience
The HX Stomp uses a small color display and three footswitches for on-device editing. Deeper editing happens through the HX Edit desktop app (USB connection required).
The Stratus® uses a Bluetooth companion app for building your pedalboard. Drag and drop effects, adjust knobs, save presets—all from your phone, wirelessly. No cables, no computer required.
For many guitarists, the Stratus approach feels more intuitive—especially if you're used to smartphones and want to tweak tones from your couch.
Verdict: Stratus wins on ease of use and wireless convenience.
Price
At ~$199 vs ~$599, the Stratus® is significantly more affordable. That $400 difference could go toward accessories, plugins, or even the Knot MIDI USB Host for hands-free control.
Verdict: Stratus wins on value.
Who Should Choose What?
Choose Stratus® If You:
- Want an expandable platform that grows over time
- Prefer wireless app control from your phone
- Value individual effects quality over amp modeling
- Want a more affordable entry point
- Like the idea of a plugin marketplace
- Want to support an open, community-driven platform
Choose HX Stomp If You:
- Need deep amp modeling out of the box
- Want built-in IR loading for cab simulation
- Need built-in MIDI I/O without an adapter
- Prefer the Line 6 / Helix ecosystem
- Want the largest possible built-in effects library
The Bottom Line
Both are excellent pedals. The HX Stomp is a proven powerhouse for amp modeling and all-in-one tone shaping. The Stratus® is a forward-thinking platform that prioritizes expandability, wireless control, and community-driven innovation—at a lower price point.
If you're the kind of guitarist who wants your gear to keep getting better after you buy it, Stratus® is worth serious consideration.
