Oh Man:
Sorry to hear you had such a misinformed goofball as an instructor Mark:
I guess I was lucky, tho I started learning to play on my grandfathers old flat top guitar upside down and backwards and got fairly good at it, the up struming was a bear:LOL. I still freak-out some folks doing it just for fun at parties just for fun.
I soon decided to switch the strings around and learn the comfortable, more natural way
All ya do is Flip the bridge and nut. I'm thinkin your teacher of the day really didn't want to teach a lefty
Later trading it in for the first production model Hangstrum (Swiss made Fender) lefty model. I like my Strat and 12 string but Man I sure wish I still had that old Axe, she was sweet
When I finially got around to taking serious lessions early 60's the teachers were always supportive and thought it was easier as we were looking at a mirror image???
