Distortion pedal from the Inna-gotta-have-a-Fuzzy effects era.
This pedal, which dates back to the era of the Yardbirds, The Doors and The Mamas and Papas, was originally part of Jordan guitar amps.
Subsequently, it became a pedal, and with its classic fuzz sound, it quickly became indispensable among the guitarists of its time. Saturated sound, it can be like the hissing of a snake or the purring of a cat. You decide.
