I think this one of the coolest most useful chords. Once I learned it I noticed it everywhere. Also known as the Jimi Hendrix chord as it’s the main chord in Purple Haze. It’s used after the pentatonic riff in The James Gang’s Funk #49. And that’s one of the best things about it. It’s great as a transition. Blackmore used it extensively after citing Hendrix as an influence (that blaring chord in No One Came from 1971’s Fireball album) and put it to great use in Deep Purple MK III when they dabbled with funk. It sounds awesome muted and coupled with a wah pedal. I think what I like about it is it sounds dirty and raw for lack of a better term. Any other players share my affinity for this chord?
