The 540STN is a double neck S series solid body electric guitar model introduced by Ibanez in 1990. It was produced in Japan by FujiGen as part of the Roadstar Pro series. It is also referred to as the 540S-TN. The TN suffix refers to the Twin Neck.

The 540STN is modeled on the 540S with a sleek, thin-edged double cutaway (triple cutaway?) body. Its lower neck has six stings while the upper neck is a twelve string.

The 540STN features a mahogany body with two one-piece maple necks attached with a traditional bolt-on neck joint with a stamped metal plate. The lower, six-string neck has a reverse headstock. Both necks have 22-fret rosewood fingerboards with dot position markers.

Both necks have Ibanez pickups. The twelve string neck has a dual humbucker configuration, while the six string adds a middle single-coil pickup. The six string neck has an Edge double locking tremolo bridge with a locking nut while the 12-string has a fixed bridge.

Controls consist of individual volume controls for each neck, a single master tone control, a 5-way pickup selector for the six string neck, a mini 3-way toggle pickup selector for the 12-string neck and a 3-way neck selector toggle.

The STW is a similar model with 6-string and 7-string necks which was produced in 1999. These two S series twin necks are among just a handful of such models sold by Ibanez since the 1970s. Since the S540SW was discontinued after 1999, the only other production twin-neck models have been 2670RE Artwood Twin reissue from 2006 and the Xiphos XPT1400TW in 2010.

It is believed that between 50 and 100 examples of this model were produced before the 540STN was discontinued in 1991.
