The electric guitar is recycled extensively in jazz, blues, and shelf and roll, and was commercialized by Gibson in collaboration with Les Paul, and independently by Leo Fender of Fender Music. The lower fretboard activity (the height of the strings from the fingerboard) and its electrical amplification lend the electric guitar to some techniques which are less frequently hand-me-down on hearing guitars. These include tapping, comprehensive call of legato through pull-offs and hammer-ons (also notorious as slurs), pinch harmonics, volume swells, and use of a tremolo Fender Custom Guitars wing or effects pedals.
Seven-strings were popularized in the 1980s and 1990s in part due to the release of the Ibanez Universe guitar, endorsed by Steve Vai. Other artists go a advancement further, by using an 8 string guitar with two extra flat strings. Although the most common 7-string unfashionable a bottommost B string, Roger McGuinn (of The Byrds and Rickenbacker) uses an octave G string paired with the regular G string as on a 12 string guitar, allowing him to incorporate chiming 12 string elements in standard 6 string playing.
