Do stereo versions of pedals run in mono in-mono out, sound worse than their pure mono versions?
I am debating selling my stereo Walrus Julianna pedal because it sounds sharper and more digital than a lot of demos of the original mono Julia, and I've noticed this in comparison videos between the two as well.
ChatGPT says it's partially because of the stereo split being re-summed to output as mono, and that the mono versions of pedals sound better run in mono for this reason.
Is this true or is ChatGPT just making stuff up like it does half the time?
Mono versions of pedals better than their stereo versions when run in pure mono?
