I have been playing guitar for a little over two years and think I'm reasonably good, but I have a question about pull-offs that has been bothering me for a long time. I have a hard time explaining it, so bear with me. I hope that if I'm doing this wrong, I can unlearn a bad habit (which is hard to do two years into the game). Thanks in advance.

Anyway, here's my dilemma. I'm talking about multiple pull-offs (we'll use a chromatic scale for this example). Which of the following are you supposed to do?

1. Place all four fingers on their respective frets, then pull of one at a time until only your index finger is remaining to let the note ring out.

Or

2. Place only two fingers on at a time. Ex. Place pinky and ring finger on fretboard. Pull off to ring finger. Place middle finger on fretboard, and pull of to middle finger. Etc.

So I guess what I'm asking is do you quickly position all fingers on their frets before pulling off, or do you position your next fingers on lower frets at the same time you are pulling off your current fingers? I know that may have been confusing, so if you have any questions as to what I mean, let me know.
