Using the Fender Pugilist Distortion Guitar Effects Pedal is easy. First, connect it to your guitar rig. You can adjust the dual gain engines and the independent tone controls on each to get the distortion sound you like. Use the Series/Blend switch to stack channels for a more intense effect, and the Bass Boost switch when you want a fatter tone. The Blend control helps you mix the channels for a perfect sound. When it comes to power, you can use a 9V battery. Just open the magnetically latched hinged battery door. As for maintenance, keep it in a dry place and avoid knocking it around. The anodized aluminum construction is durable, but still, handle it with care. If you're not using it for a long time, take out the battery to prevent any damage.
