Basic functionality of the Voicings on the MP-1 & MP-2

[INRI]

I was wondering: what is the magic of these units for them to have different voicings? How can it go from sounding like a fender clean to cranked marshall? Chat GPT was brainstorming and going all about the DSP being able to change tube bias on the fly etc. But that sounds extreme. Do any of you guys have any idea how this works?


As you may have noticed Im all out fascinated by these units even though Ive never been nearer than 500 miles to one.
