Change a pickup''s resonant frequency and tone with a loading capacitor
Quadrupling the load capacitor will lower the treble stuff above resonance by 6dB, and move the peak down about an octave (the aforementioned interwinding capacitance makes the math not exact). A lot of people don''t really understand what a tone control on a passive bass does.
