Welcome to All Music Inc's Musicdungeon, you are looking at a great piece.
This is the EarthQuaker Devices Rancho De La Luna Dirt Transmitter Electric Guitar Fuzz Effect Pedal.
The Dirt Transmitter is one of the oldest circuits in the EarthQuaker line. 
The design is Fuzz Face inspired, and the idea started when Jamie Stillman came across some very unique silicon transistors. 
These transistors are lower gain and have a warmth similar to germanium transistors when overdriven. 
But they also have the top-end grind typical of silicon-based fuzz pedals, which adds to the mids and helps cut through. 
The combination of these rare transistors and the starved voltage creates a wide variety of textures at the turn of a knob.
