This is the BBD-1, an effects pedal made in Japan by HTJ-WORKS. Its official name is Bottom Boost Driver, and it adds richness and thickness to your sound without compromising the original tone of your amplifier. The concept is: if you could only add one pedal directly to your amp, this would be it. Used as a booster for lead or rhythm playing, it clarifies the contours of your amp sound, resulting in a very pleasing tone for both the player and the listener. When used with a clean amp, it's also possible to create a crisp, light, and pleasant cutting sound. It's recommended for those who want to boost their amp's tone without sacrificing it, as well as those who aren't satisfied with studio amps or who have repeatedly changed amps. - Included: Box, warranty card Only used indoors, but there are some minor scratches on the back.
