Circuit Bending

                Circuit bending an audio device typically involves removing the rear panel of the device and connecting any two circuit locations with a "jumper" wire, sending current from one part of the circuit into another. Results are monitored through either the device's internal speaker or by connecting an amplifier to the speaker output. If an interesting effect is achieved, this connection would be marked for future reference or kept active by either soldering a new connection or bridging it with crocodile clips. 

            Often other components are inserted at these points such as pushbuttons or switches, to turn the effect on or off; or components such as resistors or capacitors, to change the quality of the audio output. This is repeated on a trial and error basis. Other components added into the circuit can give the performer more expressiveness, such aspotentiometers, photoresistors (for reaction to light) and pressure sensors.
