We set out to create a circuit that combined the singing, dynamic mid-range of germanium fuzz pedals with the gritty, full-bodied, well-rounded Muff-style fuzz distortion. Well… Eureka!
Utilizing silicon transistors in a proprietary architecture to capture the best of both worlds, the Eureka! is a phenomenal team player, flawlessly performing with a wide variety of effects, guitars, and amps, all while maintaining its distinct, head-turning personality.
The onboard three-way toggle-switch incrementally introduces more low-end, a feature especially useful for switching between single-coil and humbucker-equipped guitars, as well as adding extra body for solos. When set to the right (“lightning bolt”) position and fed with a strong enough signal, you can also enjoy its gated-fuzz response!

REVIEWS
“The Eureka is very touch sensitive, like some of my favourite Albert King tube amp distortion. With the toggle switch to the right, there’s a kind of compression there, where the attack is smeared out before the gigantic note arrives. And the power chord stuff is hilarious, huge snarly snaky stuff. Very adaptable for a variety of inputs, from high-powered pickups to single coil. I’m a big fan of JAM Pedals!” – Mike Miller
“The Eureka has a unique voice all of its own and covers a lot of bases. With tones that can easily deliver super-heavy riffs, lead lines with searing mid-rich sizzle, flat out noise annihilation and the addition of enormous bass energy when required, this is a really versatile pedal!” – James Sedwards
“Guitar, Eureka!, amp, done.” – David Torn
