JAM Pedals Eureka! Fuzz v2
Jam Pedals · pedal
The JAM Pedals Eureka Fuzz V2 is a handmade Greek boutique fuzz pedal based on the Shin-ei FY-6 Super Fuzz circuit from the late 1960s. It delivers a thick, harmonically rich upper-octave fuzz with strong midrange character and a distinctive woolly texture. The dual-octave coloring gives guitar notes a singing, almost synth-like shimmer when played in higher positions. JAM Pedals hand-assembles each unit in Athens, Greece, using carefully selected components to maintain circuit authenticity. The Eureka Fuzz V2 suits psychedelic rock, garage rock, and classic fuzz tones where upper harmonic content and mid-forward aggression are priorities. It responds well to guitar volume knob adjustments and rewards players who want a pedal with a pronounced, character-driven identity rooted in vintage Japanese fuzz design.
