These Faber Tune-o-matic Thumbwheels are machined from brass and come in a set of two to replace lost or damaged thumbwheels or can be used to provide extra support for an existing ABR-1 style bridge. To install for extra support simply remove the existing bridge and thumbwheels, screw these on to the bridge posts and then all the way down the post so they lock against the guitar body and then reinstall the original thumbwheels and bridge. The thumbwheels against the guitar body will stop the thin ABR-1 style bridge posts from leaning forward which can be a problem with that style of bridge.
These come threaded in two versions, metric and imperial, the thread on the imperial version is the standard 6-32 inch thread used on Gibson ABR-1 bridges and the metric version has a 4 mm metric thread for use with Gotoh and other 'import' ABR-1 style TOM bridges.
