Before having this pedal, I had no idea what's the difference between hard clipping overdrive and soft clipping overdrive. And the OCD belongs to the hard clipping category. In my case I mostly use it with a tube amp, which in fact, what I needed is a tubescreamer which belongs to the soft clipping category.
The sound itself of this OCD pedal is classic and nothing wrong about that, it's just for me, personally I find this sound is more useable for a bluesy rythm context, less for other situations, not evey solos. So nowdays I use it as a boost pedal mostly, putting drive to minimum and raise volume beyond 12 o'clock.
