Some will swear that this is the right way to string up an Explorer.
Funny story (at least to me):
My brother's band was playing as CBGB's back around 1981, 82.
The guitar player only had one guitar (imagine???), a white/creme '79 Les Paul Custom and asked his brother if he could borrow one of his, as he had several.
He ends up borrowing his '76 Explorer (a guitar that I would end up purchasing many years later) which was strung up as above.
Somewhere in the middle of their set, Chris (the guitar player, who went by the stage name Ivan D. Terrible Bastard) grabs the Explorer, plugs in and hears it's slightly out of tune. Of course he tries to tune it, but because of the dim stage lighting he can't see that the plain strings are wound "backwards" and keeps trying to tune.
It doesn't make sense. The more he tunes it, the worse it gets.
Now the crowd at CBGBs is getting a little impatient. This is the punk crowd after all, so I hand him back his Les Paul, which I had tuned up in the interim and he went back about his business.
Days later he's telling his brother that "there's something wrong with this Explorer," recounting the tuning issues in front of the crowd and his brother just laughed his ass off.
