This is a bar bridge that originally came with a HMG-CX model Mockingbird guitar, which was sold as a collaboration between IKEBE Gakki and Fernandes, purchased used at a guitar shop. When I modified it to resemble an MG80X, I replaced the bridge. I am selling this one because it is no longer needed. The distance between the studs is as shown in the photos, 82mm. It will be shipped in the case that came with a GOTOH stop tailpiece I purchased separately.
