Brand New Custom Series Box of Rock Distortion / Boost. This is a hand painted ONE OF ONE - Custom Commissioned One off Artist Edition Pedal. This pedal accurately replicates the sound of a cranked Marshall JTM45 non-master-volume amp. The drive tone is harmonically rich, incredibly responsive and stunningly accurate; it doesn't get any cooler than this!
The Box of Rock also contains an extremely high-headroom, unity-to-50X gain booster with nominal input impedance and low hiss. It is very similar to the SHO boost circuit, with refinements to make it sound more like a standard amp input and less glassy. The boost channel can be used alone or in conjunction with the "distortron engine" channel. The boost channel follows the distortion channel so that the distortion is able to hit your amp harder (at a higher volume) when both switches are engaged, for boosting solos and what-not.
Look out when boosting what-not. 8^)
