King had an intuitive style, often creating guitar parts with vocal nuances. he achieved this by using the open-string sound associated with Texas blues and the raw, screaming tones of West side Chicago blues. King's combination of the Texas and Chicago sounds gave his music a more contemporary feel than that of many Chicago bands who were still performing 1950s-style music, and he befriended the younger generation of blues musicians. In his early career he played a solid-body gold-top Gibson Les Paul with P-90 pickups.  He played several slimline semi-hollow body Gibson electric guitars, including an ES-335, ES-345, and ES-355. He used a plastic thumb pick and a metal index-finger pick.
