Im 43. My first guitar teacher was a sub music teacher I had in 6th grade. His name is Joe Podorsek and too my surprise was friends with as well as guitar teacher too Ted Nugent and also played guitar in some of the Motown Hits. What luck.
Our regular teacher was out for 2 weeks and her name ironically was Mrs. Pantera. She always wheeled out the Piano and we'd sing Grand Old Flag and other 6th grade early 70's standards.
Well Joe come in with his Fender Twin on Wheels and his Strat and the next two weeks we learned Mama's and the Papa's,CCR and a ton of killer guitar oriented stuff I would have otherwise never payed attention too.
I took lessons that Joe offered at the Junior HS for 6 weeks and even though I hardly progressed the basics he taught me applied to everything guitar Ive since tried or heard.
Next epiphany on guitar for me would be in 78 when I heard that damn Van Halen album. Nothings been the same since.
