I noticed this video on YouTube today. It’s a demonstration by Joe Satriani, being interviewed by Dave Martone, of his pedalboard. Apparently this was filmed in 2010 so I expect he’s using some different pedals now. There are a lot of videos about pedals on YouTube, of course, but this one struck me because it’s a relatively quick overview but it touches on an awful lot of subtle points on the use of pedals in a short space of time.
Of course, Joe Satriani is a fantastic guitarist; I saw him in concert a few weeks ago and it was great. This video is well worth watching, whether you’re new to pedals or not, and there are plenty of other interesting videos with the Satch.
