Crews do amazing guitars, but they've been doing pedals for even longer, and the work is very good. This is uses four op-amps to deliver a super transparent, very tweakable overdrive. It's similar to an OCD, but with a little less gain range, and a much more powerful EQ section. The independent boost is  winner too, it's super handy. This looks fantastic, and sounds even better.
