Yeah, this happens for me, too… Insane preset, not in a good way. It doesn't necessarily sound like it's doing anything it's not supposed to be doing. Rather, I think the feedback is set too high and it's going into self-oscillation. I've got spillover on and when I switch to 49:2 from any other active preset, it sounds like it's picking up a bit of the previous sound. If I switch from bypass, it's OK until I make any sound at all (just touching the strings), then it starts oscillating. Anyway, I think this is just a poorly written preset.
