The Ibanez SZ320 is an SZ series guitar model introduced in 2003. Features include a mahogany body with maple top, set-in mahogany neck, two humbucking pickups and the Gibraltar III bridge. Initially it came equipped with Ibanez own SZ pickups, which were replaced by the Seymour Duncan designed Duncan/Ibanez pickups.
In 2007, the SZ320 was replaced by the similar SZ320EX.
