The right side is a nice overdrive, very warm sounding for my Les Paul, Tele and Gold Foil Guitar. I use mine for low overdrive. This box feels like an amp. It can be very clean and then you can lean into it and get a little hairy
overdrive. The right side is a perfect boost. I MEAN PEEEERRRRFECT! The right side works well to boost the lft side or to boost on its own, or to stack it on top of another overdrive. I stack mine on top of The OCE Lineman or Earthquaker PlUMES! Simply Awesome!
