I am having the exact same problem. I have a two channel amp head with two separate inputs. The first input is my clean channel, which the Modfactor sounds great with. Nice clarity and warmth with my Les Paul and Telecaster. My second input is my overdrive channel, which is a stock Marshall overdrive, nothing heinous, and I cannot get ANY of the patches, stock patches, to sound good at all. It sounds like the distortion is choking on itself. I get no clarity. As it sweeps thru the low end of the effect, it distorts. On the high sweep of the effect, it has such low fidelity, it is totally unacceptable. Mind you, all I have is the Modfactor in my effect chain. Any thoughts?
