From the vendor

A great low-to-mid-gain amp-like overdrive with a 3-band EQ.

The Equinox Overdrive project is a clone of the Marshall Guv’nor / Drivemaster. It’s an overdrive with a 3-band tonestack, and it was among the first overdrive pedals to use this type of tone control, allowing for more amp-like toneshaping via bass, midrange and treble knobs. Because of this, you can get a very wide range of tones out of it and it is suitable for many different styles of playing.
