Hardware.
Essential guitar hardware and accessories including string ferrules, Bigsby rollers, pivot screws, jack plates, knobs, and luthier tools.
What to know before you upgrade.
Hardware is the connective tissue of a build — the parts nobody photographs but every tech swaps during a refresh. Aumsen machines the small pieces that routinely wear out or get upgraded: through-body string ferrules, Bigsby B5 / B7 roller upgrades, tremolo pivot screws, jack plates, knobs, switch tips, and the common luthier fixtures (radius gauges, fret levelling beams). Before ordering, confirm the hole diameter and body depth for ferrules, the roller diameter and shaft length for Bigsby rollers, and the screw pitch (imperial 6-32 / 8-32 vs metric M3 / M4) for any threaded item.
Material notes
Brass and stainless are the workhorses — brass for anything where warmth matters, stainless where it has to resist corrosion and thread wear.
