I used these on my P-Bass for a couple months, but now I am selling that bass so I put the stock tuners back on. This is the version with the Clover shaped tuning keys and 1/2" shafts.
You have to drill one small hole on the back of the peghead for each tuner for the anti-rotation screw. The main job of holding them on is through the ferrules, which tighten down with a wrench on the hex flats... very secure.
These tuners will really help with the neck dive problem so prevalent on Fenders & Squiers with the large headstock and heavy "traditional" open gear tuners, and they are super smooth in operation.
These list for $33 each, but you can find a set of 4 for about $85 plus shipping. I'll sell this very lightly used set for $69, shipped anyplace in the CONUS via USPS Priority Mail.
