This  GOTOH® GE104B ABR-1 Style Tune-O-Matic Bridge brings modern performance to a classic design. While not a direct replacement for Gibson ABR-1 bridges, it features M4 threaded posts and thumbwheels, providing a secure fit with a stud spacing of 2 29/32" (74mm) and string spacing of 2 1/16" (52mm). Its rattle-free design eliminates the need for the traditional wire, offering smoother playability and more travel room for improved intonation—all while retaining that vintage tone. Perfect for players who need precision without sacrificing classic style!
