Using the Fender Hammertone Flanger Guitar Effects Pedal is easy. First, connect it to your guitar and amplifier using the top - mounted input and output jacks. Plug in a 9 - Volt center - negative AC adaptor (you'll need to get one separately). Then, turn on the pedal using the true bypass footswitch. You can play around with the resonance and type switches to create different flanging sounds. When you're done using it, just switch it off. To keep it in good condition, avoid exposing it to extreme temperatures or moisture. Wipe it with a dry cloth regularly to remove dust. And be careful when moving it around to prevent any physical damage.
