The Eureka is an original Muff-style fuzz circuit by Greek manufacturer Jam Pedals based on a silicon transistor design.
The classic three knobs for Level, Gain and Tone and expanded by a three-way toggle switch that offers different bass settings, a useful feature for switching between single-coil and humbucker guitars or beefing up your tone. It can also produce a gated-fuzz response in the “lightning” setting (right position) – but needs a hot signal to do so.
Here are the video demos of it, we added it to our article about the best Big Muff-style pedals.
Here’s the demo we shot at our Stompbox Booth at NAMM.
Jam Pedals Eureka Fuzz, Builder’s Notes
We 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…
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!
