Hey guys, I was listening/Watching some stuff during the 75 TOTA and during YCAGWYW and Angie it sounds like Keith may be using some type of effects on his guitar. I checked the Rolling Stones Gear book and it doesn't indicate them using Phase Shifters until 1977. Can anyone verify if they were in fact using a Phase Shifter (or other type of effect) in 1975?
If not, does anyone know how he got that Phase Shifter type of sound out of the Zematis during that tour?
