Until the early 1980s, Grover Jackson worked for the guitar builder and manufacturer Wayne Charvel. Charvel made copies of the Fender Stratocaster and was the first manufacturer with a 24 frets guitar, the 'Superstrat'. In 1980, Grover started his own company and focused primarily on building individual customer requirements. One of the first customers was the guitar player of Ozzy Osbourne, Randy Rhoads. This became the 'RR' model which was based on the Flying V. or Gibson. Due to the high quality of the Jackson guitars, more and more guitar players, especially from the heavy-metal scene, had a custom-made guitar built at Grover Jackson. This resulted in legendary models such as the King V, Soloist, Concert and Dinky. The guitars were produced in San Dimas, California and later also in Ontario, California. In 1985, IMC acquired the greatest interest in Jackson and began to devote more time and attention to a more extensive guitar market. | While Jackson still makes top products, Jackson also began to produce cheaper versions of their standard designs in Asia in an effort to make their products more accessible to people with a small wallet. In late 2002 bought Fender Musical Instruments Corporation Jackson IMC, and American productions were moved to the Fender factory in Corona, California. Grover Jackson |
Unfortunally ESP didn't keep good records of old serial numbers. Many records have been lost during years and most of all were destroyed in a fire accident on late '90s in ESP Japan factory. For old guitars we can only know the exact data reading the ESP warranty card (when there is), or unscrewing the neck (if the neck is bolt on) and read.
