From the vendor
This pedal can generate every tone you need. The Crunch channel provides from soft overdrive to hard rock distortion. The High Gain channel offers from rock gain stages to high-gain shred. Additionally a Boost will add extra volume to your pedal output. This DIY version operates with 9V. The pedal has a build in +/- 9V power supply, which will duplicate the headroom compared with a regular guitar pedal.
