They tried that with me in the first grade. I was left handed to begin with. The teacher would pop my hand with a ruler when she saw me writing with my left hand. I never complied. Then, over the summer of 1971, my first cousin flipped me in the backyard. I landed squarely on a root.......with my RIGHT collarbone. It broke of course. So that was that. They had to let me be left handed then. lol
I had always known Hendrix was right handed......which to me makes his talent......no his GIFT with the guitar even more pronounced. Here's a right handed guy, who takes a right handed guitar, flips it upside down leaving it strung right handed and plays probably better than anyone ever has or ever will. I would love to have seen his transformation had he lived.
