Henretta Engineering Green Zapper Auto Filter



Configuration: As you look down at the front of Green Zapper, the LED is near the top, and the on/off footswitch is near the bottom. The input jack is on the right side, the output jack is on the left side, and the power jack is on the left side.

Power: You can only power Green Zapper with an external power supply (9 VDC) with the commonly used center-negative barrel connector. The maximum current draw is 10mA.

Circuit: The Green Zapper circuit uses a TL072 dual op amp. This component is positioned in a socket to allow swapping with other op amps for sonic experimentation. Be sure to only swap with op amps that have the same pin configuration as the TL072. If you have questions about acceptable replacement op amps, please contact Henretta Engineering.
