Bought for a project that never materialized. Brand spankin new. They are the gotoh type that Ibanez ,MTD, Pedulla etc use. I think the model # is gb-7 though i'm not positive. One more thing is that they are convertible ie the bass and treble ones can be switched to your preference. I also have an Ibanez sb-7 for 40.00 shipped to your door. Specs at www.ibanez.com Pics available on request.
