The S320 is an S series solid body electric guitar model introduced by Ibanez in 2007. It was initially made in South Korea, but production moved to Indonesia for 2008. It was among the most affordable models in the S series.
The S320 features a mahogany body bolted to a maple neck with a 22-fret rosewood fingerboard with offset dot position markers on at the twelfth fret. Components include a pair of Ibanez Infinity humbucking pickups and the ball-bearing pivot ZR double locking tremolo bridge with removeable ZPS2 tuning stabilizer.
At least two spot models based on the S320 were offered: the chameleon finished S320SP and the S320DX with sharktooth inlays.
The S320 was discontinued after 2009 and replaced with the S420, which is nearly identical except that it has 24 frets.
