The Ibanez S320 is an S series guitar model introduced in 2007. Features include a mahogany body, two Ibanez Infinity humbucking pickups and the ZR tremolo. Since its introduction it has been the most basic S model with little to no inlays and a raw 'weathered' finish.
In 2008 production moved from Korea to Indonesia. For 2010, the S320 was discontinued and replaced with the S420. The S420 is almost identical to the S320 in features and appearance, except that it has 24 frets.
At least two spot models have been based on the S320: the chameleon finished S320SP and the S320DX with sharktooth inlays and a solid black or white finish.
