Jimi Hendrix completely rewrote what was possible with a guitar. He pioneered the use of feedback, distortion, and wah-wah pedal as expressive tools rather than accidents, and his performance at Woodstock in 1969 is still studied today. Songs like “Purple Haze” didn't just top charts, they changed the entire direction of rock, blues, and funk music forever. Rolling Stone named him the greatest guitarist of all time. He was self-taught, left-handed, playing a right-handed guitar flipped upside down, and somehow made it all look effortless.
