At the very beginning of the Stevie Ray Vaughan song Couldn't Stand the Weather, Stevie uses this effect that I'm dying to know what it's called. He uses it in the intro and also on the lead guitar throughout the song. Does anyone know what it is? Is it a pedal effect or is it from an amp setting or what? Listen to the lead guitar especially in the intro and please someone tell me what that's called. There are many other songs on which SRV did it, but I know for sure it's in this one. Tin Pan Alley is another one. Can anyone help me?
