Overview
This CNC-machined hardware part is a drop-in upgrade path for players chasing a better-specified replacement for a worn or under-spec OEM part. Each piece is machined in-house and hand-inspected before it ships.
For broader category context — geometry, spacing conventions, and alloy differences — see our hardware overview.
In the package
Machined part in a labelled bag, protected against shipping transit
Printed spec sheet with dimensions and any matching OEM reference
Required mounting hardware where relevant (springs, claw, grub screws)
QC sign-off — every batch is hand-inspected before packing
Installation notes
Dimensioned drawings are published on this listing and in the spec sheet. Before installing, verify the fitment details below against your guitar — a five-minute measurement with callipers prevents the most common returns. If anything looks off, email us at contact@aumsen.com before you drill, file, or plate.
Compatibility cues
Cues are derived from the part title and the hardware category fitment list. Always confirm dimensions against your guitar.
Material & build
Brass and stainless are the workhorses — brass for anything where warmth matters, stainless where it has to resist corrosion and thread wear.
Verify before ordering
Ferrule outside diameter and body-route depth
Bigsby model (B3 / B5 / B7) and roller length
Screw thread (imperial or metric) and head profile
