Amp model decoder
The device list tells you nothing unless you already know the amp. “Watt D103” and “CA John’s 2C” are obvious to someone who has owned one and useless to everyone else.
29 of 90+ amps, and we say which
The community wiki documents these; the rest of the factory amp list has no published decoding we could find. We would rather show the gap than fill it with plausible-sounding guesses — the value of a decoder is entirely in being able to trust it.
Unlike the Nano Cortex's factory capture decoder — which is our own reading of deliberately obfuscated names — these mappings are documented per amp by the community wiki. They are sourced claims at community reliability rather than guesses, and several decode themselves once you see them written down.

“Basslad” is the giveaway, and the jumped variants are the classic Bassman trick of patching both channels together.

Marshall JCM800 2203
4 × EL34
2203 is the JCM800's actual model number, so this one decodes itself.

Marshall JTM45 2245
2 × 5881
TM45 is JTM45 with the J moved. 30 W in the wiki's spec, which is lower than the JTM45 is usually quoted at.

UnverifiedThe wiki contradicts itself here: the description says the EL34 revision, the spec box below lists 6L6 power tubes. We have not resolved it, so no tube type is given.

“Vishnu” stands in for Shiva — a different Hindu deity, presumably chosen for exactly that reason.

Roland JC-120 Jazz Chorus
- Normal channel
- Effect channel — not modelled
Solid state
The effect channel is not modelled, so the chorus everyone wants a JC-120 for is not in the amp block. Use a chorus device instead.
Quad Cortex Wiki: Virtual Device ListThis table covers 29 models. The Quad Cortex ships 90+, so most of the factory list is not decoded here — not because we skipped it, but because no published mapping exists for it. If you know one of the missing ones first-hand, tell us and we'll add it with a source.
