ABSTRACT:
A variable resistor adapted for use in tone control has an insulating substrate plate on which are formed two conductors. On the conductors are formed respective insulating films and, on the insulating films, a common resistance body. The ends of the conductors are positioned at an intermediate portion of the resistance body, so as to be short-circuited by a slide as the latter is brought to the intermediate portion of the resistance body.
