The S520EX is an S series solid body electric guitar model introduced by Ibanez in 2005. It is similar to the S470, but has an dual humbucker pickup configuration, black hardware and a special inlay. Other features include a mahogany body, Wizard II neck and the ZR tremolo.
The S520EX is the second model known by that name after a 2002 model. A special limited version of the S520EX was issued in 2007 as the S07LTD.
The S520EX was discontinued after 2009 in favor of a new series of 24-fret S models.
