Question, what is it you like about multiband distortion on guitar?
It makes amp sims sound delicious, but I've been doing this since the 80s, when I came up with the Quadrafuzz. I stopped using guitar amps in 1968 so I've always wanted to get "my sound" before hitting the input jack of a flat response amp. So far multiband distortion is the best option for getting the sound I want.
I'll be doing a demo at some point of the difference between single-band and multiband amps. I sent a quick demo to Line 6 in the spirit of "Hey, do you guys know Helix can do this?" and they were pretty impressed.
You can think of multiband distortion as cleaner than conventional distortion, but dirtier than hex distortion where each string distorts individually.
