My 4KFF (Four Knob Fuzz Face) gives you a massive tone palate to work with. Glitchy, velcro gooey goodness to that sweet fuzz the circuit is well know for. The standard Fuzz and Volume controls are there as are a bias (glitch/velcro) and a tone filter that lets you remove or add in the amount of low end you want. Super versatile!
