How to read the measurements
- String pitch
- The centre-to-centre distance between neighbouring strings at the bridge. A string-pitch value is different from the total outer-string spread.
- E–E spacing
- The centre-to-centre distance from the low E to high E on a six-string guitar. Other string counts use their stated outer-string endpoints.
- Post spacing
- Stud or pivot centre-to-centre distance. Screw spacing may mean adjacent screws or the two outer screws; the record preserves the source’s definition.
- Arm thread
- Diameter and pitch must both match. Push-in, collet and threaded designs are distinct. Do not assume the same thread across a brand’s models.
- Undocumented
- “Not documented in cited sources” means the research has not established the value. It is not a zero value or a compatibility claim.
Manufacturer-source reference; verify the exact variant and its dimensioned drawing before drilling or ordering a replacement. Dimensions, routes, arm fittings and hardware can differ by production year, string count and OEM version. Diagrams and manuals open at their original sources.
