Jackson is a guitar manufacturer originally owned and operated by Grover Jackson, a partner of Wayne Charvel of Charvel Guitar Repair. It started with the creation of the concord later known as the "Rhoads" V model guitar, originally designed and used by guitarist Randy Rhoads. Grover put his name on the Rhoads rather than the Charvel name because he felt the design was too shocking for Charvel's regular customers. This model inspired Grover to start the Jackson guitar company. Wayne Charvel sold his interest in the Charvel name to Grover Jackson on November 10, 1978. The shop was located in Glendora, California (while using a PO Box in neighboring San Dimas) and manufactured guitars in this location from 1979 to 1986, when the Company merged with IMC (International Music Corporation), a Texas based importer of musical instruments. The factory then moved to Ontario, California.
