Troubleshooting

If there is no output on one channel…

• Check all of the cables and swap the input, to see if the problem moves from one channel to the other.
• Verify that headphones are good with another source.

If there is no output at all…

• Check to see if the power LED is lit, and check the power connection.
• Verify that power is on, using another pedal.
• In the case of Strymon™ power supplies (Zuma™, Ojai™,) make sure the power is off, and the headphone is connected, before powering up the supply.
