Description
The JAM Pedals Eureka! is an all-analog fuzz pedal engineered to bridge the gap between two traditionally opposing eras of dirt: the dynamic, vocal midrange response of a vintage germanium fuzz and the colossal, full-bodied saturation of a silicon Muff-style fuzz-distortion. Handcrafted in Athens, Greece, the Eureka! uses a proprietary silicon transistor architecture to capture the best of both configurations, delivering an incredibly versatile, high-headroom fuzz that functions as a flawless team player anywhere on your pedalboard.
Traditional fuzz circuits are notoriously finicky, often collapsing into harsh static or losing their distinct character depending on the amplifiers, buffers, or pickups feeding them. The Eureka! circumvents these issues entirely. It retains its touch-sensitive, head-turning personality whether you plug it straight into a clean tube amplifier, run it after a buffered signal chain, or stack it alongside your favorite overdrive pedals.
Interactive Three-Way Bass Voicing & Gated Fuzz Modes
The user interface provides immediate, straightforward control over output level, gain, and high-frequency tone shaping, while the heavy-duty three-way toggle switch alters the foundational low-frequency response of the circuit:
-
Center Position (No Symbol): Delivers a balanced, standard bass response. This setting provides a focused midrange punch that allows single-coil pickups to slice through a dense live mix without muddying up the low end.
-
Left Position ("!"): Introduces a tier-one bass boost (+1). This setting adds extra weight, thickness, and body, making it ideal for fattening up single-note solos or matching the output characteristics of humbucker-equipped guitars.
-
Right Position ("Lightning Bolt"): Engages a maximum low-end sweep (+2) for massive, room-shaking power-chord riffs. Furthermore, when the pedal is hit with a high-output input signal in this position, the circuit shifts into a highly musical, gated-fuzz response where the attack is compressed right before a giant, sustaining note blooms.
Studio Utility & Efficient Performance
The Eureka!'s unique voice excels at handling everything from touch-sensitive, Albert King-style tube amp breakup to flat-out wall-of-sound distortion. Built with tour-grade durability in mind, the low-noise analog signal path draws a remarkably low 8mA of current, allowing it to interface perfectly with standard 9V battery operation or modern isolated pedalboard power supplies without introducing digital noise.
