The Eureka! is a versatile silicon fuzz-distortion that combines singing, dynamic midrange with the weight, grit and sustain of classic Muff-style circuits. Its proprietary architecture stays responsive and distinctive across different guitars, effects and amplifiers, making it an unusually adaptable fuzz for both rhythm and lead work.

A three-position bass switch moves from a focused core voice to progressively heavier low end, helping match single coils, humbuckers and solo sounds. At the maximum bass setting, a strong input signal can push the circuit into a gated, spluttering response. From searing mid-rich leads to huge, snarling riffs, Eureka! keeps its own unmistakable voice.

“Relic” Eureka! details

Hybrid fuzz character
Silicon transistors are arranged to combine germanium-style dynamic midrange with full-bodied Muff-inspired fuzz-distortion.

Three bass settings
Middle position applies no bass boost; the first boost adds low-end weight; the maximum setting adds still more bass and can produce gated fuzz with a sufficiently strong input.

Controls
Level controls output, Tone shapes the frequency balance and Gain sets saturation.

Designed by musicians, for musicians.

From vintage-inspired classics to boundary-pushing analog designs, each JAM pedal is crafted with care to inspire your sound and spark your creativity.
Designed by musicians, for musicians.

JAM pedals began in 2005, when guitarist and sonic explorer Jannis Anastasakis set out to build pedals that didn’t just sound good, they sounded alive. What started as a one-man workshop in Athens has grown into a passionate team of builders, artists, and musicians who still make every pedal by hand, one at a time.
