\rHi Davis:
The VKR120 is a Resistor based non impedance matching volume control. These are a make before break design, so there is no connection between clicks and it does completely disengage when turned all the way counterclockwise. Depending on the setting of the master volume the control may become inaudible before the last click. But is not completely off until totally turned to the last click. The Impedance Matching Transformer style volume controls do not turn off at all except the SVC205 which has an actual on off switch on the plate below the rotary knob. Note the Resistor based volume controls in theory tend to sound better. There have no high or low end roll off meaning they have a broader Frequency Response.
