This one's simple. It's a booter/overdrive pedal, with a unique twist.
It has volume, tone, and gain controls. The tone control rolls off highs to the point all that's left is low end, which interacts well with fuzz pedals.
There is a 3-way mini toggle on the side. When centered, the pedal is in booster mode. When the gain is cranked, the boost will dirty up, but you can get a bit of clean boost as well. With the switch up, clipping diodes reduce the headroom (asymmetrically), creating more distortion. With the gain all the way up, it can border on fuzz. With the switch down, only the high end is clipped. The low end remains in tact. Just for you bass players.
