Regarding the "Reverse Hendrix" thing, I've sometimes wondered if the reason Jimi preferred playing right-handed Strats left-handed was simply that the reversed nut would allow an exceptionally low action for the thin E, B & G strings, and an abnormally high one for the bass strings. He made extensive use of "hammering on" on the thin strings, and he used to really pound the bass strings.
Or it may simply be that he learned to play on reverse-strung guitars, and found it easier to keep doing that.
I wasn't like he was short of a quid; if he really felt he needed to play a proper left-handed guitar, he would have been doing so.
