I really enjoy Griff's videos and tips. I'm currently learning classical guitar and would like to pickup blues soloing, but am wary of DVD instruction. My concern is picking up the wrong technique with no feedback from an instructor. For example, I tried to practice pull-offs from B string but keep striking the E string as well. I know it is a technique, but do you have any means of providing specific tips?
With an electric guitar, you don't have to do a "big" pull-off get the note to ring. A little flick that stops short of the high-e string will do just fine.
An alterative, which should also work with acoustic, is to hammer the note with the pad of your finger and actually use a little of the pad on the top
side of the string so it is plucked when you pull the finger
up and away from the B. This should keep your finger well clear of the e-string.
Also OK to mute the e-string with an unused finger as the pull-off is taking place. Flatten out your fretting hand a little more than you otherwise might. (As Larry pointed out.)
As always, practice will naturally guide you to ways that prevent making noises you don't want to make.
