One of staples of my pedal board is my Fulltone OCD, a dependable, solid overdrive pedal which if I could only have ONE pedal, the OCD would be hands down the pedal I would choose.
The overdrive through this pedal sparkles and is super responsive whether it be full chords or single notes. The sound doesn't get muddy or mushy. Key to my sound. In fact, my OCD was used extensively on our EP, Made in Cabrasfornia.
