The fender bass is a classic instrument, since its debut in the early 50’s it has been used in nearly every style of bass playing, and every genre of music. Vintage fender basses now cost upwards of $5000 , on the low end of the spectrum, sometimes less, but classic era basses cost the remortgaging of a home.
I myself would love to have capacities to afford such luxuries, but in the absence of such funds I found a great way to upgrade my Mexican made p bass, the Wilkinson 4 saddle bass bridge!
My p bass is an early Mexican made one from 1992, the neck is a more j bass profile, and it has shaller tuners which are solid, and these had a thin layer of finish on the neck which feels very nice. The bridge has always been ok and reliable on it, but it seemed to be a chrome, or nickel plated brass. The Wilkinson bridge has larger unplated brass saddles and upon installation and first playing it feels and sounds livelier and louder. These are marketed as a classic style bridge and it is very accurate.
