If I sat in one of Pebber's videos and practiced until I could reach his speed....I don't know if I could ever reach it ? I can't guess how fast I could potentially play ? I have no motive to shred right now.
Everyone is different, maybe you just want to shred ? If so, stay in the vids and practice daily until you can reach high speeds. Note: Don't just practice the scales Pebber demos over and over,,,Trill and Spider heavily. After awhile you will see your hand moving all over as if it had its own mind. Also, make sure both of your hands are synced up. What good is a Shawn Lane left hand when you have a Fred Durst right hand.
Overall message: Have a reason for everything you do while practicing guitar.
