I have been a fan of Nels Cline for sometime now. He never ceases to amaze and inspire me. Now I admit he is not for everyone, but I dig him. I was just reading through his tech page on his site, and although it is a bit dated it is very interesting. Check the linky below. I really enjoyed his section on amps and how he threw caution to the wind and played whatever was available on a particular tour. I like his attitude on the matter.
I just have to get to see him live someday.
