The Crazy Tube Circuits Constellation is a germanium fuzz and booster from the Greek boutique manufacturer, using OC41 germanium transistors to produce rich, warm, organic fuzz with the harmonic complexity and dynamic response characteristic of premium germanium fuzz designs. Delivers the classic warm germanium fuzz character associated with 1960s Tone Bender and Rangemaster-style germanium circuits in a handmade boutique format. Made in Greece by Crazy Tube Circuits.
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.
