I just got done goofing around with a Landgraff Dynamic Overdrive... my first whack at this pedal. Man, this thing really is one sweet little box. It nails so many tones... and where I might stack two dirt boxes... this one seems to do it by itself. I'm also surprised how well this thing cleans up for an op-amp based circuit. It's not like a fuzz clean up, but also doesn't turn to mud either. Big thumbs up. Anyone have any "sweet spot" setting they like?
