My first guitar that I would give credit to is my American Fender Strat that I bought in 8th grade. Saved up all my Birthday/Christmas/everything else money to buy it and my dad loaned me a couple hundred under the condition that I pay him back monthly. Still have that guitar today and it's the one I use every day to practice on. Been around 12 years I think since I got it.
In between that beginner guitar and my Strat, I would use my Dad's '57 Martin acoustic. Guitar teacher always liked it when I brought that guitar in......at the time I had no idea why.
