Using the Fender Hammertone Space Delay Guitar Effects Pedal is easy. First, connect it to your guitar and amplifier using the top - mounted input and output jacks. Then, power it up with a 9 - Volt Center Negative AC Adaptor (which you'll need to get separately). Once it's on, you can use the Pattern & Mod Switches to create different delay effects. For a natural sound, start with the default settings and then adjust as you like. When you're not using the effect, just step on the true bypass footswitch to go back to your normal guitar tone. As for maintenance, keep the pedal clean and dry. Avoid exposing it to extreme temperatures or moisture. If you notice any issues, check the connections and the power supply first. That's all you need to know to make the most of your pedal and create awesome music.
