John Valentine Carruthers (born 1958 in Wortley, West Riding of Yorkshire) is an English musician, guitarist, and composer.

In the early 1980s, he joined Sheffield band Clock DVA after the release of their second studio album.

Carruthers teamed up with his friend drummer Paul Ferguson to form the band Crush with American musicians.

[8] He used different audio effects including MXR Flanger "to get a really dirty sound," Drawmer Stereo Compressor, Eventide Harmoniser/Delay, Yamaha 1010 analogue delay and Ashly Parametric.

He used the "Roland Jazz Chorus with a splitter box, and put one signal to the Peavey for a lead sound, and the other to the Marshall which I have really distorted".
