The Charvel Model 4 is a (super)strat guitar made in Japan in the eighties by the company Kyowa - Shokai under contract by IMC (International Music Corp). Grover Jackson chose a pointy headstock design that was popular among a new generation of guitar players. The Charvel Model 4 is at the top of the bolt-on neck models of the Charvel Model series. It has an HSS pickup configuration. The J-200 pickups are actually Dual coils in a single coil housing. Besides the passive pickups the Model 4 also featured Jackson's JE-1200 active preamp with mid boost. The neck was a Quarter-Sawn maple neck, with a compound radius 12"-16" maple finger board.
The 1986 version has a Kahler 2520 tremolo and pearl dot inlays but the following years the Model 4 featured a Jackson JT6 Vibrato and sharkfin inlays.
