Most adjustable bridge ever made, which is a good thing in some ways, and bad in others. Very heavy, adjustable spacing, adjustable everything. I bought this with the intention of putting it on my Ibanez 6, but now I just need the money. It has never been installed on a bass, but it is a little oxidized. I don't have the allen wrenches, the mounting instructions or the mounting screws. Make me an offer! Here is a picture.
