Description
The Gibson ABR-1 is a Tune-o-matic guitar bridge sold as a full assembly — bridge plus mounting posts (studs) and thumbwheels — in chrome finish (Gibson part PBBR-010). Designed in 1954 by Gibson president Ted McCarty, it has been standard on countless Gibson models for over 60 years. The bridge uses closed-bottom construction with unnotched, individually adjustable saddles for per-string intonation adjustment; string height is set via the thumbwheels, and the posts mount directly into the guitar body. Key measurements: 2-1/32 in (51.56 mm) string spread, 12 in (304.80 mm) saddle radius, 2-29/32 in (73.66 mm) post spacing, and 6-32 x 1-1/16 in post threads.
