A Leftie in a Right-Handed World
Jimi Hendrix, famously, played guitar left handed – that is he fretted notes with his right hand and strummed the strings with his left hand. But left-handed guitars were few and expensive, so Hendrix took an ordinary right-handed Fender Stratocaster, flipped it upside down, so that the tuning pegs were on the bottom, and restrung it.
Doing this changed how the guitar sounded. A Fender Stratocaster has three pickups (electric microphones that produce the signal fed to the guitar’s amplifier), with the rear pickup set at an angle to the strings. Reversing the guitar meant that this pickup took its signal from the higher strings further up the fretboard, producing a sweeter tone. By reversing the guitar, Hendrix also changed the relative distance of each string from its pickup, thereby altering the mix of sound in the guitar’s signal to the amp.
Another effect of reversing the stringing on his guitar was the highest strings, which on a normal Stratocaster are the longest, became the shortest on the Stratocasters Hendrix played. A shorter string requires less tension to tune it, making the string easier to bend and thus easier to play. This change also altered the amount of string between the nut at the end of the fretboard and the tuning peg. Although the nut prevents this length of string actually playing, it produces overtones when the string is plucked. Changing the length of these parts of the strings also contributed to the unique Hendrix sound.
