Pinnick was born on July 23, 1953, in Van Nuys, California, and took up the guitar at the age of seven.^[1] An early example of his professional guitar work can be heard on Herb Alpert's single "Rise," which reached No. 1 on the Billboard Hot 100 in October 1979.

After guitarist Donnie Dacus left Chicago in 1980, Pinnick was hired as a session musician for the album Chicago XIV. In his biography Street Player, Chicago drummer Danny Seraphine remembers how Pinnick, like [Chicago's] original guitarist Terry Kath, played "guitar with plenty of fire" and had "similar mannerism". Robert Lamm, in an interview given at the time, confirmed that Pinnick's resemblance with Kath was at times "spooky".^[2] Pinnick toured with Chicago from 1981 through 1983. By the time Chicago 17 was released in 1984, Pinnick was listed as a member of the band. However, Pinnick himself is quoted as saying he was never a full-fledged member.^[3] He left Chicago in 1985 and was succeeded by Dawayne Bailey.

Pinnick's other recording credits include work for one-time Chicago frontman Peter Cetera, Chuck Negron, Chet McCracken and Rick Devin. As of 2008, he continues to do session work in Los Angeles, where he is also the co-owner and operator of a recording studio.
