I’ve noticed that there are a few 90s extreme metal “cult classic” amps that have had a bit of a revival recently, with several companies now producing preamp pedals based on these amps. This renewed popularity would seem to make these amps good candidates for adding as amp devices (not captures) to the Quad Cortex so more people can access and tweak the tones from these amps. Here are the amps I’m thinking of, along with examples of the preamp pedals that have been made for them:
