• Use a continuity test to confirm that your switch is labeled correctly.

​

• If your LEDs are still receiving power while the switch is off check to make sure the ADTL082 chip and or the battery are flipped to the right positions.​

​

• If for some reason your guitar has a different output level than 100-300 mV, simply adjust your potentiometer. Reducing its resistance will increase your gain, while increasing it will reduce your gain. To monitor this, you can use a modeling software such as pspice or Multisim to see the gain of the circuit. Or you can build the circuit, send it an input signal with a waveform generator, and then measure your output using an oscilloscope. The picture below is our model in Multisim and the transient analysis of it with a 340 Hz, 300 mV sine wave input.

​

• When you construct the amplifier circuit on its own PCB use the continuity test on all connections to check for discontinuities and fix them accordingly.
