I shared guitars before I actually got one of my own and played a guy's Silver tone and played another guys Danelectro 12 string and it was at about age 17 that I actually started playing.

I was producing demos for a band that was called Physical Ed. Out of production of demos I went and did a few jam sessions with then in Northern California clubs, but I never actually toured with them.

When I started reaching teenage years, I listened to everything that was on the radio like everyone else did, which was Chuck Berry, Beach Boys and then of course The Beatles, Stones. And of course in the 60's, I was completely blown away like everyone else by Hendrix, Cream, Deep Purple, Jeff Beck and all of that... so those were my influences.

I don't recall getting a first guitar.

Reading and writing music is a wonderful way of getting ideas in your head down to someone else who reads and writes, but if you don't read and write, and the other musician you're playing with are trying to express something who doesn't read and write, than it's a question of "I wrote" so that you must learn from listening and from understanding where that's coming from.

In the absence of evidence to the contrary, always assume you have the upper hand.

I would say seeing the original Yardbirds with Jeff Beck and Jimmy Page at the old Fillmore was a pretty powerful influence on me.
