Of Stevie Ray’s many finest hours, tonally speaking, the standout is the blistering solo tone on the title track of Couldn’t Stand The Weather – unparalleled for fire and finesse anywhere else in his recorded career.

Surprisingly, that molten tone over brother Jimmie Lee’s B minor chord breakdown isn’t played on ‘Number One’ either - instead, it’s the bridge pickup of ‘Charley’, a white Strat-style guitar (with a rosewood neck and three Danelectro lipstick tube pickups) through two ’63 Fender Vibroverbs (five and six off the production line), a 150-watt Howard Dumble Steel String Singer, a Fender Vibratone supplying the rotating-speaker simulation and soul to burn. The essence of SRV? It’s right here.
