This is an Ibanez Iceman type guitar body with an extremely large cavity on the underside meant to house electronics for custom modifications. It can be left out or left empty if desired. One example constructed and designed by PJ Carruth can be previewed on YouTube at http://youtu.be/dCRxa7BbJfc . This body is meant to be used with a common Fender Strat style neck which makes it easy to find compatible parts. The bridge is a standard Floyd Rose type tremolo. Available without control holes for custom applications and electronics.
