Would using a Mu-metal core produce a better bass guitar sound?

Connecting for example a 5H inductor to the bass pickup, (in parallel or shunt).

Would Mu-metal produce a great bass sound but with less excessive high frequency content?


Mumetal has the property that after a frequency, it's inductance is decreasing so that the inductive reactance (in ohms) remains content [1].
