Some of these may seem obvious, but they are all issues we have encountered on several occasions.

  • Check your connections. INPUT is on the RIGHT side, and OUTPUT is on the LEFT side.
  • Make sure you are using the correct type of power supply: regulated 9V DC center-negative.
  • Try the pedal by itself — just instrument ► pedal ► amp (or direct). If the problem disappears, then it's probably not the pedal.
  • Cables and power supplies often fail or become intermittent. We recommend that you always have spares handy. Here are some troubleshooting tips:
    • To isolate the problem, patch around pedals one at a time until the problem disappears. Then try to reproduce the problem with the simplest possible signal chain.
    • To check for a bad cable, flex the cable (especially near the plugs) while running signal through. If it cuts out or causes hum/buzz, it's bad. Do not toss it in a box with good cables!
    • To check for a bad power supply, swap it with a known good supply.
  • Does your pedal pass signal, but the LED not light? This means the supply voltage is too low and your power supply may be bad.
