I'm sure I'll be trying my favorite tones, especially if they're isolated.
Here's a quick rundown off the top of my head:
Eric Johnson lead on Cliffs of Dover (intro), clean tone on various tunes
SRV rhythm/lead circa Couldn't Stand the Weather
Alex Lifeson on Spirit of Radio, Limelight, La Villa Strangiato
Jimmy Page - Heartbreaker, Whole Lotta Love, Ten Years Gone
Adam Jones - Jambi
Brian May - multiple
David Gilmour - multiple
Joe Bonamassa - multiple
Depending on how labor intensive the process is, I could see myself going crazy and putting together a comprehensive list of all my favorites tunes/tones. If it takes a lot of work, I'll probably stick to my top 5 or so (or just copy them from others who already did all the work)
Ultimately I only play a couple of tones most of the time, but it would be nice to have these at the push of a button or pedal.
