^^^ This. I was already a fan of Rush, Geddy, and his tone before the album was released, but when I heard Exit Stage Left - that was when I decided to buy a Rickenbacker.Geddy Lee's Rickenbacker rock tone on Exit Stage Left. One of my favourite Rick rock tones ever recorded. I'm not sure what the backline was, maybe Ampeg.
From what I have read, Geddy's gear at that time was: A pair of Ashly SC-40 preamps, using the Ric-o-sound stereo output to have each pickup go to a separate preamp, followed by power amps (I think Crown), and then speaker cabs. The Ashly that the bridge pickup was sent to, had an overdrive mod (diodes).
