Stratus makes sense when you want to add native captures and custom effects to a board you already like. Its three NAM A2-Lite blocks and FX Builder 2.0 share one small mono pedal. GP-200 combines its modeling and converted-capture workflow with an expression pedal, more footswitches, and recording connections in a larger floorboard. Compare the job each would do in your rig before comparing the number of features.
Three NAM models, one Stratus preset. With the latest Chaos Audio app and Stratus firmware 1.0.100, Stratus runs up to three NAM A2-Lite models simultaneously in a single preset/chain, using your own uploads or TONE3000 captures. Each NAM block now uses roughly half the CPU it used before this update; other effects still share the pedal’s processing budget.
As of September 17, 2026, Stratus is the only factory-built compact pedal under US$300 we’re aware of that natively runs three NAM A2-Lite models simultaneously in one preset/chain. Its price is $299. See the latest Stratus and FX Builder 2.0 update.
The short version
- Stratus: Three native A2-Lite blocks and custom effects within an existing mono board.
- The alternative: GP-200 provides expression, several footswitches, and recording/stage connections in a larger floorboard.
- Start with the rig: decide which sound, control, or connection you need before comparing catalog totals.

Conversion vs native, explained fairly
GP-200’s NAM workflow converts files to SnapTone through the matching desktop editor and firmware. Stratus plays every NAM capture on TONE3000 natively in A2 Lite mode after loading from the app. The library has 600,000+ amp and pedal captures, all retrained to A2 with both Lite and Full modes. Those are different preparation steps; this article has not measured an audible penalty from conversion.
What the floorboard buys
GP-200’s expression pedal, eight switches, display, stereo/balanced outputs, effects loop, and USB interface are useful if you want those functions in one floor unit. For a player who already has the preferred controls and recording setup, adding a smaller sound-building pedal can be a more direct fit.
What the pedal keeps
For a particular sound, describe an effect in FX Builder 2.0—for example, a delay with darker repeats and gentle movement. Audition the result, ask for a change, then install it in your Stratus chain. Pedal captures can feed an amp capture, with other effects sharing the available processing power. Once installed, your sounds run locally and can be recalled without a phone or internet connection. Hear FX Builder 2.0 examples and explore the workflow. The examples on that page are software-rendered demonstrations.
FX Builder 2.0 is now on mobile. Build effects directly in the Chaos Audio app for iOS and Android, then use them in your Stratus chain alongside NAM captures. These current app screenshots show the builder and a finished effect.


On stage
Stratus recalls 14 presets from its footswitches and up to 128 through USB-MIDI with a host for conventional controllers. GP-200 provides more switches and onboard expression. Stratus uses a 9V center-negative supply meeting its current requirement or supported USB-C power; verify the available current on your board instead of assuming any existing 9V outlet will work.
Cost of ownership
GP-200 and GP-200X are different offers. The GP-200X artist-edition listing should not be used as the standard GP-200 price. Compare the exact model, regional price, taxes, and included accessories. Stratus is US$299 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. See the product page for configuration, regional pricing, and shipping estimates.
Which should you buy?
Choose Stratus when saving board space and shaping a particular sound matter more than consolidating every connection. Build a capture chain, create the effect it needs, and keep the pedals and controls you prefer.
Choose GP-200 when expression, several switches, and its audio connections are the functions you want in one floorboard. Confirm the matching editor and firmware for converted captures.
