This is a roller saddle-type Tune-O-Matic bridge that was installed on a GODIN semi-hollow guitar. [Specifications] - Roller saddle type - Color: Chrome - Includes posts (studs) - Engraved on the back: BH-1993 - Post spacing: Approx. 74mm - Condition: No noticeable scratches, good condition. Polished with a cloth, so it's shiny. This is a roller bridge primarily used to enhance the smoothness of Bigsby-style tremolos and improve tuning stability. The saddle part where the strings rest has a roller structure, which reduces string binding when using the tremolo. With a post spacing of approximately 74mm, which is standard for Gibson-style guitars, it is compatible with Les Paul, SG, ES-335, and other models. Would this be suitable for someone with a Bigsby-equipped guitar? I removed it because I replaced it with a standard fixed bridge (GOTOH GE103B). Therefore, it will be shipped in the case that the GE-103B came in. Thank you for your consideration.
