The SZ series is a line of solid body electric guitar models produced by Ibanez which was introduced in 2003. It is the third series of Ibanez S series guitars with a hard-tail bridge instead of a tremolo. It spawned the similar SZR series in 2008.
Like its predecessors, the SF and SC series, the SZ series based on the classic Ibanez S shape, but is even more of a departure from the original design. The SZ has a thicker body and flat back, a standard set-in neck and the Gibraltar III bridge also introduced in 2003. Like the SC, the SZ has a 25.1 inch scale neck instead of the 25.5 inch of the standard S.
In 2008, the SZ series was replaced by the very similar SZR series. While that one was discontinued again in 2010, the SZ made a slight return with the GSZ220A in Japan only.
