I do use my pinkie on the lower strings when soloing--guess I just never realized it. I guess I was just thinking more in terms of bending the higher notes. As far as chords, blues comping, bass runs, boogie patterns, etc., I use my pinkie constantly. I must have "man hands".
Just ask Bluesman. When we met in Wausau, I crushed his hand when I shook it!
As far as the pinkie on the picking hand goes, I encourage students to anchor that to the high E string when reaching to the 4th, 5th and 6th strings for reference. Otherwise, they have a tendency to "float" and have to stare at their hands. Obviously, if you are strumming this won't work.
NPB, what you are referring to is called a reinforced bend. That also includes the thumb over the top. Watch most guitarists solo and you will see that the index, middle and ring all move in unison like one big finger.
gsj, I love it. "Two were enough for Django"--it's so true though. Django was amazing. Did you happen to catch "Django Mania"? Some of those people went to such extremes to play like him, even taping their fingers!
Bluesman,
Are . . . you . . . sayin' there's no . . . Santa?
No, I haven't watched the video yet. I have a very slow computer and it takes me like five hours to download five minutes of video. Maybe on Friday, I'll check it out.
