yea, ive got to say that this es very helpful, but not for everyone. ive been playing the git stick for about four years and i can most definitely hold my own technical-wise, and i dont even own a metronome. i just do it all in my head, and even with weird time sigs i usually find myself out allright, and ive never found any riff i cannot physically play due to my learning style. to each his own, though.
