I think the fundamental part of my technique is my vibrato.
A wah-wah is important as well. I love it; it makes the guitar scream.
I have done some things that I'm very proud of. I don't think you can say any more than that, really.
Once I've settled on something I'll stay with that at least throughout the whole tour.
While I was with Procol Harum, the only time I'd see my guitar was either when I walked onstage or in the studio.
During my early period I had custom-made overdrive stuff because I didn't like what they were making at the time.
