Earthquaker Devices Cloven Hoof
This pedal has actually been discontinued as it is the second version of the Hoof, but wow does it sound good. They installed a set of four specially selected Silicon transistors for cleaner cleans, higher gain, improved temperature stability, and a grittier, grindier, nastier fuzz tone with over 4x the gain of the original Hoof.
Try it out and snag it before you can't find them anymore!
