JAM set out to create a circuit that combined the singing, dynamic mid-range of germanium fuzz pedals with the gritty, full-bodied and well-rounded Muff-style fuzz distortion. Well...Eureka! Utilizing silicon transistors in a proprietary architecture to get the best of both worlds, the Eureka! is a phenomenal team player, flawlessly performing with all kinds of different effects, guitars and amps, all-the-while managing to maintain its distinct head-turning personality. The onboard three-way toggle-switch incrementally introduces more low-end, a feature extremely useful for switching between single-coil and humbucker equipped guitars, as well as beefing things up for solos! When set to the setting, and sending a strong enough signal its way you can enjoy its gated-fuzz response!
