I started around 1975 on an old, cheap Spanish guitar one of my uncles gave me and my sister to learn with a few chords drawn on a piece of paper. The guitar had been restrung with metal strings and our fingertips were massacred... We just wanted some backing while we sang. I learned by trying each chord on the songs until I thought it was good. With time I figured how it worked. I was not interested in soloing. But In a few years things changed. My parents bought me the electric guitar in my avatar in 1980 (a cheap Strat copy). When asked, I always say I play guitar, I don't specify "electric". It would be weird to imagine someone who claims can they play guitar and find he/she clumsy on an acoustic. Maybe it's because at the time it was considered normal to start from acoustic/classic/spanish before moving "on" to electric guitar.
