From the vendor

Parallel (transparent) overdrive effect. Able to naturally boosting an amplifier or other overdrive pedal, only slightly coloring the sound. Turning the Drive knob to the right mixes it into a clean overdrive signal, keeping it dynamic and readable. Therefore, the pedal works well as an effect overdrive. Option of switching the type of clipping diodes has been added (1N34A/BAT85). Power supply: regulated mains adapter 9 VDC. The dimensions of the main PCB 50 x 91 mm. Enclosure type: Hammond 1590B.
