What real life hardware are the classic and vocal modes emulating on the pro c2? They sound 1176ish but I don’t know. Any ideas anyone?

I don't think there's a lot of modeling going on, but probably some inspiration that's explanatory from the labels.

The classic mode is the only feedback mode of ProC2, so i guess it bares some resemblance to 1176 in topology which is also feedback type, but 1176 is generally much faster.
