I got my first acoustic when I was a junior in high school, a Harmony made out of construction-grade plywood. About six months later I got my first electric guitar (a Gretsch Roc Jet that I never should have sold) and amp (a Sonax solid state POS that deserves it's own ring in hell).
A weird Kingston with a large metal scratch plate- bought it from a neighborhood kid- i believe he sold it to me without his dad knowing about it (it was his dads guitar). I played that thing through my stereo and through a panasonic boombox for a while before my folks caved in and got me a real guitar- a Sigma acoustic. Sometime in the mid 80's.
