Pots - ever wondered?Why do we call the volume and tone controls on an electric guitar pots? They are round and sort of cylindrical in shape, a bit like a pot, but that is not the reason. The working part of a pot consists of a fixed resistive track and a moveable contact. When the knob of the volume or tone control is turned, the contact moves round the track, which has a variable resistance. In electrical terms, a variable resistor is called a potentiometer, which common usage shortened to a pot. What our pots actually do is put more or less resistance between the current the pick-ups are producing and the amplifier, which is why we like the volume turned right up full, when the most current is getting through, meaning a bigger sound. |
