The JS20S is a Joe Satriani series solid body electric guitar introduced by Ibanez in 2008. It is a signature model of American guitarist Joe Satriani. It was initially produced in South Korea, but production was later moved to Indonesia.
The JS20S features a basswood body bolted to a maple neck with a 22-fret rosewood fingerboard with pearloid dot position markers. Components include an Edge III double locking tremolo bridge with a locking nut and dual Ibanez Axis humbucking pickups mounted in chrome pickup rings.
The JS20S is a mass-market version of the much more exclusive (and expensive) Japanese-made JS20th. Both models were produced to commemorate the 20th year of Satriani's relationship with Ibanez.
