Rubber Ducky, you’re the one!! The Eureka! Fuzz is the perfect marriage of classic fuzz circuits. Juiced by silicon transistors, this pedal achieves the sweet midrange of a Fuzz Face and the full-bodied thickness of a Big Muff. With the straightforward controls of Level, Tone, and Gain, this little duck is super easy to dial in. It also plays well with any guitar we’ve thrown at it. There’s a three way toggle that increasingly adds more low end content which is perfect for beefing up single coils. Lastly, if you ever wanted to run the Eureka! on battery power, you can open the enclosure and insert a standard 9v battery, but not before removing the little yellow rubber surprise!
