Is this "ripple" effect/artificact sounding like a digitial clipping sort of? I hear these with the Fender style amps that are mildy or more driven. There is no clipping input nor output, and these artifacts the end of the signal is annoying. Doesn't happen (or I do not hear) with higher gain amps. Turning the Ripple setting down seems to help but doesn't go completely away. Will do more testing and follow up in the next couple days.
