Using the Fender Tread-Light Volume/Expression Pedal is easy. First, connect it to your guitar or other devices using the appropriate cables. The top-mounted jacks make it convenient to plug in. You can adjust the treadle torque to your comfort level. To use it as a volume pedal, simply step on the treadle to control the volume. For using it as an expression pedal with other effects pedals or keyboards, connect it with a 1/4' TRS cable. The switchable under-treadle LED helps you see the pedal's status. When the LED is on, the pedal is active. Remember to use a 9-Volt Battery or a Center Negative AC Adapter (not included) to power it. Avoid exposing the pedal to extreme temperatures or moisture. To maintain it, keep it clean and dry. If you're not using it for a long time, store it in a safe place.
