Band-aid mod

The band-aid mod is a stabilizer tuning trick that involves cutting small pieces from an adhesive fabric bandage and sticking them to the PCB exactly where the stabilizer wire taps down when a key is pressed. The fabric pad cushions that contact point, reducing the tick or click sound the bare wire makes against bare PCB.

It is popular specifically because it is cheap and uses a household item rather than a specialized keyboard part, making it an easy first mod for someone just starting to tune stabilizer sound. It is usually done alongside lubing the stabilizer wire and housing, since the two mods address slightly different noises: lubing reduces rattle and scratch, while the band-aid pad reduces the tap sound at the contact point.

Placement matters more than most people expect. The pad has to sit exactly under where the wire lands, which takes some trial and error, and using too many layers can raise the wire enough to change how the stabilizer sits. Pre-made band-aid mod style kits are sold for people who want the same effect without cutting up bandages themselves.
