I built the od2. It was a ts clone with some some extra voicings. It also had a electro harmonix lpb-1 clone on the other side. Great pedal. It will realky push a preamp with lots of headroom. I also did the germanium(?) fuzz and the tremelo pdl. I only have the od2 anymore. I wanted the crybaby rebuild kit but afraid it will change it too drastically.
