Funny about instruments. I played trumpet for years, right handed of course, and I am a southpaw. Switched to French horn, and it was left handed, again, no biggy. For Stringed instruments, however, I am pure lefthanded, playing guitar and banjo (albiet not worth a damn) restrung. I also had to get a left handed acoustic bass which is a pain in the butt. I can pick up a right handed guitar and play a few chords upside down, but it sure isn't very eficient!
