Welcome, you are looking at a really cool piece.
This is the Electro-Harmonix Octavix Octave Fuzz Pedal.
This pedal by EHX takes the classic and proven sounds of a fuzz pedal with an octave up and improves it with some modern adjustments.
The 3 controls are simple to find your sound - volume, boost to adjust the fuzz, and octave to adjust the amount of octave mixed in.
This pedal even lets you choose whether you want to run the power rails at 9V or 24V. At 9V, this pedal has classic, saggy fuzz tone. At 24V, the sounds is much tighter and delivers a richer octave tone.
This is a great innovative pedal that improves on a proven guitar effect tone.
