Step 8 - Troubleshooting
1) Power up the board with the IC (op amp) not in the socket. Confirm that the LED lights when the cable is inserted into the input
jack. This "activates" the circuit by creating a metal to metal connection that functions as a switch. If the LED doesn't light, click the
stomp switch. If it does not light after that, check all the solder connections. Make sure there are no loose solder joints or unintended
bridges between connections.
*NOTE*: It is important to unplug your input cable when not using the pedal to preserve battery life. If left in, the circuit will stay on,
and continue to use the battery.
2) Test voltage across pins 8 and 4 of the op amp socket using a voltmeter (+9V and GND). Looking from above with the circular
indent at the top, pin 4 is the lower left pin and pin 8 is the upper right. It should read something close to 9V (polarity doesn't matter for
measuring voltages, other than displaying positive or negative values). If all good, unplug the battery, insert the op amp into the
socket, and play test. If it doesn't work, confirm that all the parts are installed correctly according to the given diagrams.
