This classic circuit, originating in early 1967, is an analog board with the properties of a frequency doubler, envelope generator, and amplitude modulator with additional frequency shaping filter circuits. It was famously used by Jimi Hendrix in many of his recordings, such as ‘Purple Haze,’ ‘Fire,’ ‘One Rainy Wish,’ ‘Little Miss Lover,’ ‘Little Wing,’ and ‘Machine Gun.’ The pedal produces a clean fuzz that will allow the octave sound to go through, and when you put some chord on it, you can hear that great ring modulation sound happening. We have added an “octave lift” switch so you can use it without the octave overtones for added flexibility. This easy-to-build board will allow you to have one of the most collectible vintage pedals out there. The controls include Fuzz and Volume. With this classic circuit, you can create unique tones and sounds that will make your music stand out.
