Tailpiece used on the early 425, 450, 460, etc. with the standard 6-saddle bridge.
Mounting screws are included.
Because these tailpieces were installed inconsistently, you must provide us with the distance from the center of the crown on the 12th fret to the center of the three tailpiece mounting holes in the guitar body so we can put the dimples in the right place relative to the tailpiece (proper intonation and all that). If this is new construction or if you don't mind potentially moving the tailpiece, leave it blank and we'll put the dimples in a standard location and you can position the tailpiece accordingly.
Because this tailpiece is machined specifically for your guitar using the measurements that you provided, it is not returnable.
