King was one of the founding members of Strawberry Alarm Clock, formed in Los Angeles in the mid-1960s. The band's largest success was with a song that King co-wrote, "Incense and Peppermints" (but, along with keyboardist Mark Weitz, did not get credit). The song reached No. 1 on the Billboard Hot 100 in October 1967. Their follow-up single, "Tomorrow," reached No. 23 on January 1. King met the members of Jacksonville, Florida-based Southern rock band Lynyrd Skynyrd when the band opened up for Strawberry Alarm Clock on a few shows in early 1968. It wasn't until 1972 that he joined Skynyrd, replacing Leon Wilkeson on bass, who left the band briefly. Wilkeson rejoined the band, and King switched to guitar, creating the triple-guitar attack that became a signature sound for the band.

​

His guitar playing and songwriting skills were an essential element to the band's first three albums: Pronounced Leh-Nerd Skin-Nerd, Second Helping, and Nuthin' Fancy. King co-wrote "Sweet Home Alabama," and his voice counted the "one, two, three," before he launched into his famous riff to start the song. In addition, Ed King provided the band with riffs and solos that defined its distinctive "southern sound" including, but not limited to the riffs for "Poison Whiskey," "Saturday Night Special," "Mr. Banker," "Swamp Music," "Whiskey Rock-a-Roller," "Railroad Song," "I Need You" and "Workin' For MCA", "The Ballad of Curtis Loew", and more. King decided to leave the band in 1975 during the "Torture Tour." He was replaced in 1976 by Steve Gaines, who was killed in a plane crash along with lead singer Ronnie Van Zant, and his sister Cassie Gaines. on October 20, 1977. Coincidentally, Gaines and King share the same birthdate. King's influence on the band's sound was more noticeable with their release of Gimme Back My Bullets in 1976 in which he was not present. The tone and song composition differed considerably from the three previous albums where he was an active contributor.

King was one of the guitarists for the reunited Lynyrd Skynyrd in 1987, and played a major role in the reunited band. He was forced to leave Lynyrd Skynyrd again in 1996 due to congestive heart failure. He left on the understanding that he would rejoin once he regained his health, but the band did not allow him to rejoin
