I bought this bridge thirty years ago and the store owner knew nothing about it. No markings/stampings/scratchings of any sort on it.
It's obviously eight string compatible; the area beneath the ball ends used to have a projecting ledge with five mounting holes in a Fender compatible spacing which I cut off because using those holes left the bridge way too far forward on the body to intonate. I drilled and countersank new mounting holes further forward ala BA2.
Does anybody know who made this thing?
