The Charvel Model 3A 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 3A differs from the Charvel Model 3 in that it has an HH pickup configuration with two Jackson J-80C humbuckers. The neck was a Quarter-Sawn maple neck, with a compound radius 12"-16" maple finger board.
