First off, there are different techniques which can be used to tap your guitar neck. The way Van Halen tapped was by using his index finger to hammer onto the guitar fretboard, and then pulling off his finger. The way he held his pick enabled him to pull off this technique. While most people hold the pick between the side of the index finger and the thumb, Van Halen held the pick inbetween his thumb and the tips of both his index finger and his middle finger. That way he was able to quicklylet go of the pick with his index finger and tap the guitar while still holding onto the pick with his middle finger and his thumb.
