From the vendor
Clone board of the Son of Kong EQ/Gain pedal. Apparently, this is the EQ section that Frank Zappa ran in all his guitars. Runs on a standard 9v supply, offering up to 15db on channel 1, or 35db of boost on channel 2. Can run on up to a 36v supply voltage for way high headroom, or to pummel your amp into submission with up to 55db of boost(!). Also offers a DI output, so you can plug in direct to the board. The EQ section offers a wide variety of tonal bliss, including great cocked wah sounds. A great "Swiss Army Knife" of a circuit.
