In mid-1966 he left the Bluesbreakers, whose members had grown to include Jeff Beck and Jimmy Page. The band he formed with bassist Jack Bruce and drummer Ginger Baker would become Eric's best-known band, and rock's first-ever supergroup, Cream. Cream became the "pre-eminent (best) rock trio of the Sixties"; the name came from its members being among the top session musicians in England. They played both their own songs ("Strange Brew", "Sunshine Of Your Love", "White Room") and cover versions of other people's songs ("I'm So Glad"). Like his contemporary Jimi Hendrix, Clapton helped to pioneer the use of the wah-wah pedal. He played a famous guitar called The Fool. He also developed what he called the "woman tone" on his guitar and used it to great effect. For instance, at one point during the song "Tales of Brave Ulysses", he combines the woman tone with feedback (overdriven amplifier) to create a unique sound.
