JAM Pedals Eureka
Jam Pedals · pedal
The JAM Pedals Eureka is a germanium fuzz pedal from Greek boutique maker JAM Pedals, using vintage germanium transistors to produce the warm, soft-clipping fuzz character associated with 1960s germanium fuzz designs. JAM Pedals is known for sourcing premium vintage components for their germanium-based designs, and the Eureka delivers the warm, dark, temperamental character of vintage germanium fuzz circuits with Greek boutique handmade quality. The Eureka suits blues, vintage rock, and psych rock applications where the specific germanium warmth is the tonal goal.
