Every number anyone publishes, with the source attached. Where Neural DSP's own documents disagree with each other, both readings are noted rather than averaged.

- Factory captures
- 25 — 20 guitar, 4 bass amps, 1 bass overdrive
The FAQ's “20 guitar plus 5 bass” and the device list's “4 bass amps” are the same five: counting the Anima Fuzz bass overdrive reconciles them exactly.

Numbers that don't exist
These aren't omissions from this page. Neural DSP has never published them, and a blank in a spec table is an invitation to invent a figure — a few invented ones are circulating as fact.
- DSP chip, core count and clock speed
- Signal-to-noise ratio
- Total harmonic distortion
- Dynamic range
- Frequency response
- Bluetooth version and profile
- What USB input channel 2 carries
- Country of manufacture
- The NanOS 1.1.0 changelog
- Maximum length and sample rate for user IR files
- Centre frequencies and unity positions of the BASS, MID and TREBLE controls
- Whether a saved capture can be re-trained or re-calibrated
These are not omissions from this page — they are things Neural DSP has never published. The tone-control frequencies are the most consequential absence: owners have explicitly asked for that documentation, because without it you're tweaking a three-band EQ whose behaviour you can only learn by ear.
- Official
- From Neural DSP's manual, FAQ, guides or release notes.
- Community
- Reported by owners. Corroboration, not a primary spec.
- Our reading
- Our interpretation, not something Neural DSP states.
- Unverified
- We could not confirm this, or sources disagree.
