    The normal bass has
    # 1) 250 ohms potentiometers and a .047 micro farad capacitor.
    To go deeper we use
    # 2) a .10 cap and 250 ohm pots.
    Let's go the other direction and use
    # 3 ) a .022 cap and 500 ohm pots.
    What is the sound of each and are there sound clips somewhere accessable?
    what actual use would # 2 and # 3 be good for?
     
  2. Standard pots for passive pickups are 250k or 500k, not just 250 or 500. The k denotes that we multiply by 1000. So in Ohms, it's 250000 or 500000.

    The resistance of the pots changes the resonant frequency of the pickups slightly. Likewise, the capacitance in a tone control moves the cutoff frequency up and down. Think of it, crudely, like playing around with the frequency knob on a parametric EQ.

    So then in Godsbassman's example:- a .10 cap (instead of an .047) and 250K pots will get you a deeper tone?
     
  4. Yeah.
