hey peeps:) i was at a friends house today he rocks on guitar well he was doing these cool harmonics where he uses his thumb and index finger to make harmonics on invisable frets (past the last fret on ur guitar neck over the pickups and so on)basicaly his index finger is used as a fret and his thumb is placed behind it and it plucks the string while his index finger is in light contact with the string!! its sounds awsome!! and looks awsome!! he was doing harmonics all over the place.. give it a try it takes a lil time to find the harmonic points!! does anybody here already use this technique?
