6" x 43" x 4"
This thing is totally insane. It weighs 16 lbs and sounds really good. For the tuning pegs I had to drill big holes through solid steel, quite the ordeal. The 'bridge' is fours screws coming from the back side, and each one has its tip filed into a U shape so the string fits in to it. There is no nut - the strings just slide through a respective hole at the top. It has an active EMG pickup which is mounted on top of the strings. A video is here.
