What is shin-ei companion fuzz?

The Shin-Ei Companion Fuzz is an analog guitar effects pedal that was originally manufactured in Japan in the late 1960s and early 1970s. It was designed to produce a characteristic fuzz sound that was popular at the time.

The pedal features two distinct modes of operation: "fuzz" and "treble boost". The fuzz mode provides a thick and warm distortion effect that is ideal for classic rock and blues guitar tones. The treble boost mode offers a more focused and pronounced distortion effect that is well-suited for lead guitar solos and cutting through a mix.

The Shin-Ei Companion Fuzz is known for its distinctive appearance, which features a red and black checkerboard pattern on the front panel. It is also highly sought-after by vintage guitar pedal collectors and musicians for its unique sound and historical significance. Some notable artists who have used the Shin-Ei Companion Fuzz include Jimi Hendrix, David Gilmour, and Eric Clapton.
