The Green Pony is a pedal based on the Maxon OD-820, which was created as a response to the popularity of the Klon Centaur. While it is not a clone of the Centaur, it does feature a dual-ganged drive knob concept that allows for a range of tones from clean boost to overdrive. The pedal also includes an internal charge pump that increases the voltage for extra headroom.

One key difference between the OD-820 and the Centaur is the distortion circuit. The OD-820 uses Maxon’s Tubescreamer circuit, which offers more flexibility for DIY modifications. The dual-ganged drive knob on the OD-820 works differently than the Centaur, as it does not shunt any signal to ground. This means that the tone and pick sensitivity remain intact throughout the entire rotation of the drive knob.

The BYOC Green Pony is based on the OD-820 but includes additional stock options for Tubescreamer mods. It features a NORM/THIN/FAT switch to modify the bass response and gain, as well as a LED/NONE/Si switch to modify the clipping. The Si (silicon) clipping is asymmetrical, and the value of one capacitor in a low pass filter has been changed to reduce the mid-range hump and preserve treble.

Another notable feature of the OD-820 is its JFET input buffer, which uses the 2SK246 transistor, similar to the BOSS FA-1 FET PreAmp.
