about arm placement:
so i've been switching around to find a good position for my arm. i was wondering should the elbow be floating in front of the guitar, or aligned with it or maybe even behind it? i know this influences the angle your wrist has to bend. in the book it almost looks like michaels' elbow is behind the top of the guitar.
another quesiton is regarding upstrokes: they're just too wimpy sounding and when i try to add more force, it gets out of control. how would i achieve a more even tone without compromising control?
