    just curious about this product. says it makes a tone control much better and more usefull.

    Q-filter
     
  2. Ah, their website description is terrible :D Check out the Q-filter sticky at WildeGate.

    The Q-filter is an inductor. Used on the tone pot without a cap or resistor, the Q-filter (sometimes called an L-filter in this context) lowers the inductance as you move down the taper, which is like "taking winds off" of the pickup. If you use it with a cap and resistor, you're essentially creating a crossover network that retains the lows you get normally while giving you the effect I described above the "crossover". It's very useful for getting full, balanced tones, because many amplifiers like to see a relatively high impedance in the lows but don't produce highs well with higher inductance pickups.

    thanks for that description!

    can someone compare this to a standard tone knob?

    i am wondering if this would be a tonal upgrade for a passive jazz bass.
     
  4. While it's reducing the general level of the highend, it's also extending it outward. The exact effect is going to depend on the pickup's inductance and cable capacitance, but the resonance you hear from their interaction will become smoother as it's shifting upward. If you have a resonance between 3-5 kHz (pretty common), especially in the bridge position, the tone will become smoother and more pleasant. Most tone controls would just attenuate the highend, especially at 4 or below, which is where the effect of the capacitor comes into play.
