| I use a 4-knob Hoof and it's one of my favorite fuzzes for sure. Super thick and growly in the mids with the Shift knob set CCW, very articulate and quiet even at high gain settings, sounds killer with the gain set low, and it works great with my active 5-string.
There's something about the germanium/silicon hybrid design that sets the Hoof apart from other Muff variants I've tried/own. I highly recommend it, especially if you already like the Green Muff. |
