The Guitar Factory Parramatta is the western suburbs' longest continuously trading music store. Originally trading as Watsons Music from the early 1960's the store was purchased by Ross and Paul Chalker in 1972.

The current owners, Stan Mobbs and Lewis Mallia, took over the store in 1985. The store has since gone from being solely a guitar store to a full line music store supplying Drums, Keyboards, P.A. Recording equipment and Computer assisted music.
