The SZ320 is an SZ series solid body electric guitar model introduced by Ibanez in 2003.
The SZ320 features 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.
The SZ320MH is a similar model without the maple top.
The SZ320 was replaced for 2007 with the similar SZ320EX.
