Sporting the same four-knob layout as its black-and-red predecessor with a new limited run of coveted OC75 germanium transistors, the Keeley Holy Fuzz summons warm, vintage, Velcro-style tone in a boutique package. Built with a reconceived circuit board specially-designed for the Mullard/Philips transistors, the ripping, gated tone on tap in this pedal is a surefire addition for any fuzz enthusiast.
