The schematic of the Distortus Maximus guitar pedal – the first pedal from Krank, a true “monster” with a high level of gain. Many guitarists note it not just as an ordinary pedal, but as a device with a rich harmonic spectrum.
The Distortus Maximus is equipped with a three-band equalizer, a bypass switch, and is powered by a 9V DC adapter or battery. It is capable of both amplifying a clean signal and creating a saturated sound with powerful distortion.
The cost of this pedal is in the range of $150-200. If your budget is limited, you can try to assemble it yourself.
