Like the title says, how do you like the hight of your guitar/lenght of your strap when you're standing up playing?
Are you into the Slash thing where the guitar hangs below your knees and you have to pull it up on your hip to reach the high notes, or are you more like a Beatle that wears his guitar inside the armpits?
Personally I dig the Slash thing. I like the look of a low hanging guitar, but I must say I find it rather difficult playing a very low hanging guitar.
I think it looks kinda silly when a rock guitarist has the guitar sitting too high. The only one who can pull this off still looking good is Tom Morello.
