This item is over 20 years old but in very good condition. The back cover of the enclosure has a signature from Mike Fuller, and although difficult to see, the serial number is handwritten on the circuit board. Similar to how the OCD is more of a distortion than an overdrive, this also distorts more than an overdrive, approaching distortion levels. Even with Vol and Gain at full, it's noise-free, and some people might even consider it a distortion. What's distinctive is that while pedals like the Rat and BD2 sound like *those* pedals, this one makes your amp sound like its gain is fully cranked. The manual uses a Mike Fuller-esque expression, saying it "makes the amp obey," and I think that's accurate, as the sound pressure and resolution increase significantly. This is a valuable early model, so please consider it. Negotiations and holds are not possible.
