Wilde pickups (Bill Lawrence) Q filter, use instead of tone cap

This is a special circuit that makes your humbucker clean up like a single coil. Includes a capacitor and resistor that came with it.

The Q-Filter is generally wired as an LCR network - a 1.8 Henry, low Q noisefree inductor in series with a .02 micro farad cap in parallel with an 8 kilo ohm resistor. Taking the place of the capacitor wired to the tone pot, you can gradually decrease the impedance of the circuit but maintaining a slightly higher impedance below 1100 Hertz. Also available without the cap and the resistor to gradually decrease the impedance of the pickup.

The EQ system is the most versatile system to alter the sound of a guitar and can be used for multiple functions. The basic components are a 1.8H low Q inductor in series with a capacitor and a variable resistor (the tone pot). We used to ship it as a complete pre-tuned unit to replace the cap at the tone pot, limited for one basic function. However, in conjunction with different pickups in different positions, it's much more versatile when the inductor is separated from the cap, as shipped now. In the past, this caused severe problems when players used the wrong caps and resistors, especially when the EQ was wired to a switch only. The system must be wired to a control or you totally limit its functions, as follows:
