This is great if you’ve got 15 minutes. Paul Davids is a guitarist on YouTube. Here he plays what he considers to be the 80 greatest guitar intros. He plays in chronological order, from memory, in one take. He uses one guitar and a pedal board, and he’s able to approximate many different styles and sounds. It’s pretty amazing the variety of noises he wrings from his rig. I found the video surprisingly compelling. So I’ll link it, and you can check it out if you want. I hope your day’s been going well.
