What is the meaning and use of lo-impedance pickups?
Langcaster pickups have a resonant frequency much higher than standard pickups of say 750 Hz. Langcasters are 65,000 Hz without the capacitor. When the copper wire turns are reduced from 5000 to 120, the self resonance goes way up. This is because there is far less inductance (what coils are) which is proportional to the square of the turns. So when you have halve the turns and you get a quarter of the inductance. You have 120/5000 = 1/50th of the turns so you get 0.000576 of the inductance and 1/50th the capacitance. This gives a very high resonance frequency which is why our pickups are so clear. The signal in normal pickups has to go through a Mile of copper wire first.
