EVH (Eddie Van Halen) revolutionized guitar playing with his innovative finger tapping technique, which he 'erupted' onto the fretboard in the late 1970s. His tapping style, particularly showcased in 'Eruption', became his signature and influenced countless guitarists. SRV is Stevie Ray Vaughan, MAB is Michael Angelo Batio, and Satch is Joe Satriani, all legendary guitarists but not associated with pioneering tapping.
