5.1 Channel Switching
One of the footswitches is typically assigned to channel switching. Pressing this switch will toggle between the clean and overdrive channels (or similar channel configurations) of your amplifier. The specific channel controlled by each switch may vary depending on your amplifier model.
5.2 Reverb Control
The other footswitch is generally used to engage or disengage the amplifier's built-in reverb effect. Pressing this switch will turn the reverb on or off, allowing for dynamic changes to your sound during performance.
Note: Refer to your specific amplifier's user manual for detailed information on how the footswitch functions are assigned and configured.
6. Compatibility

- Marshall DSL40C
- Marshall DSL15C

Important: Compatibility may vary with other models. Always consult your amplifier's manual or Marshall's official support for confirmation.
7. Maintenance
To ensure the longevity and optimal performance of your PEDL-91004 footswitch:
- Cleaning: Wipe the exterior with a soft, dry cloth. Avoid using abrasive cleaners or solvents, as these can damage the finish.
- Storage: Store the footswitch in a dry environment, away from extreme temperatures and direct sunlight.
- Cable Care: Avoid sharp bends or kinks in the cable. Do not pull on the cable to disconnect it from the amplifier; always grasp the connector itself.
- Inspection: Periodically check the cable and connectors for any signs of wear or damage.
8. Troubleshooting
If you experience issues with your PEDL-91004 footswitch, consider the following:
- Footswitch not responding:
- Ensure the footswitch cable is securely plugged into the correct input on your amplifier.
- Verify that your amplifier is powered on and functioning correctly.
- Confirm that your amplifier model is listed as compatible with the PEDL-91004.
- Incorrect function:
- The assignment of functions (e.g., which switch controls channel vs. reverb) can sometimes be configured on the amplifier itself. Consult your amplifier's manual.
- Intermittent operation:
- Check the footswitch cable for any visible damage or frayed wires. A damaged cable may need replacement.
- Ensure the jack connector is clean and free of debris.
If problems persist, contact Marshall customer support or an authorized service center.
