The SA420X is an SA series solid body electric guitar model introduced by Ibanez for 2002. It is one of only a small handful of models in the SA series that was made in Japan by FujiGen.
The most notable feature of the SA420X is the SAT30SX (a.k.a. Double SAT) non-locking synchronized tremolo bridge with integrated piezo pickups which can offer an acoustic sound. It has a sculpted mahogany bolted to a maple neck with a 22-fret rosewood fingerboard with white dot position markers. Other components include dual Ibanez Vintage humbucking pickups and Gotoh tuning machines.
Controls consist of a volume, tone and 5-way selector for the magnetic pickups, a separate volume for the piezo pickups and a 3-way toggle to select the output: piezo, mixed, or magnetic. The piezo pre-amp requires a 9V battery. Two output jacks allow you to separate the piezo from the magnetic/ mixed output.
The SA420X was discontinued after 2004. A quite similar model, the SA320X was introduced in 2004.
