The Cartographer preamp with both bright switches (high-shelf caps) engaged is more a 2204 than whatever the Brit 2204 is, the problem is Cartographer's poweramp sucks, the full amp sounds broken but the preamp alone is gold.
Mark IV Lead was modeled with the Presence
Pushed which removes negative feedback, but Rhythm 1 poweramp doesn't have a push/pull on Presence and has the classic IIC+/III poweramp response which is already modeled.
Mark IV Lead preamp + Mark IV Rhythm 1 Poweramp = Mark IIC+, I confirmed with the schematics of both.
Then of course the option to use Preamps or FX Send from real amps with Helix/HX Poweramps instead of buying expensive Load boxes for recording or quiet practice, the most common Poweramps are already modeled.
Preamp pedal -> HX Poweramp model -> flat solid-state poweramp -> cab.
And many other scenarios where Poweramp models are useful.
Sleeping on gold...
