What if High Z-Mode sounds exactly like Mid Z-Mode?
If your pickup is a non-traditional design with a low amount of coil inductance and a low amount of capacitance, then the High Z-Mode resonant frequency could be located at a frequency too high for your speaker system to respond to. You can change the capacitor value on the circuit board; this will bring the resonant frequency into a range where you can hear it. For more info read the Installation Instructions.
