This bridge is a direct replacement on Gibson guitars with an ABR-1 bridge or with our special conversion post on guitars equipped with the Nashville bridge. The body of this bridge is CNC machined from a billet of Cold Rolled alloy steel under rigid quality control standards at every level of production. This is the only alloy Steel bridge available. Gibson and the other aftermarket bridges are cast from a zinc alloy, brass or aluminum which causes heavy dampening to the critical overtones that support the fundamental.
