Using the Fender Hammertone Chorus Guitar Effects Pedal is a breeze. First, connect your guitar to the input jack and your amplifier to the output jack. The top - mounted jacks make it easy to set up on your pedal board. Then, plug in the 9 - Volt Center Negative AC Adaptor (you'll need to get one separately). Use the type and tone switches to adjust the sound according to your preference. When you step on the true bypass footswitch, the pedal goes into bypass mode, giving you your original guitar sound. As for maintenance, keep it away from moisture and extreme temperatures. If it gets dirty, you can use a soft, dry cloth to clean it. Don't try to open the pedal on your own as it might void the warranty.
