Guitarists might kill me. Willie, for sure.

Okay.. so, I'm trying to learn guitar in 3 days. Today is one of them. Fingertips on left hand oughta be bleeding, but they refuse. Must to succeed!!

The song I'm trying to learn can be heard HERE . So.. while I play bass.. I can't hit the same levels on bass as can on guitar.. and it's essential I do this on guitar for me to pull this thing off.

If anyone's got tips or tricks ..let me know. I nabbed this image from somewhere online for chords to use.
