Nels Cline of Wilco (et al.) has a tech talk section on his site that's been making the rounds on the guitar blogs. I guess its a bit peculiar that an artist expounds in detail on his pedal board (although John Frusciante did recently in GP Mag, listing each effect, song by song through the entirety of Stadium Arcadium ad naseum that had even me glazing over, and I like his solo albums and this sort of guitar geekery).
But I think some are missing Cline's point. Scroll down and check the Amp du Jour section to see how he fared touring without his own amp. He's definitely in the "plug in and play" camp and sees effects as gravy. Yummy, yummy gravy.
