|A Gibraltar Custom bridge on a XPT700FX (as part of a string-through setup)|
The Gibraltar Custom is a fixed guitar bridge used on various hard-tail Ibanez models. It was introduced in 2003 as a special bridge for the new MMM1 Mike Mushok signature model. Special features of the Gibraltar Custom are the increased intonation travel and a metal 'sustain block' below the bridge, routed into the body.
The Gibraltar Custom is solely a guitar bridge, meaning that it does not anchor the strings to the body itself. Therefore it has to be combined with a separate tailpiece like the Quik Change III or has to be used in a string-through-body setup like with the MMM1.
A seven-string version for the XPT707FX was introduced in 2008 as the Gibraltar Custom 7. Other guitar models with a six- or seven-string Gibraltar Custom include the MMM1, Prestige SZ models and X series guitar models.
