Finally you can quickly see for yourself which system you prefer. You will not need any tools or special skills to install this, just plug it in. Installation process takes about 20 minutes. Simply insert your pickup wires into the screw terminals, tighten the screws with the included screwdriver and plug the pickup toggle switch and output jack into the circuit board. Only the highest quality parts were used here, Switchcraft toggle and jack and CTS potentiometers.
