ahhhh the good Line6 sounds... awesome cover, flawless ! it permitted me to learn the song some time ago, thank you ! which stringe gauge did you use ?
roy michael That's a fret wrap sir and it's for killing the ringing sound that's heard after picking the strings it brings more of a crisp sound to your playing and yeah he's pinching the harmonics on either the 3rd or 4th fret on the A string that's if he's using standard tuning maybe not and the tabs you can find on ultimate guitar tabs man you'll have to purchase the app on your phone.
