Compensated Nut For Bass?

Funkfingers

For years, Ernie Ball Musicman has been supplying bass guitars with a compensated top nut, similar to the Earvana for guitar.

Does anyone manufacture aftermarket compensated nuts for bass guitars?

There's an outfit called AxeMasters that do brass and bone compensated bass nuts, from the USA.
