LM317T Voltage Regulator with Pass Transistor

Using a P90 in the Neck of a Tele, we show the volume change that the VVR will do. We start in this Trainwreck Liverpool clone with the voltage normal and the VVR off. Then you see that guy with the guitar turn down the voltage to about 1/4-1/3-ish voltage
