Using the Fender Santa Ana Overdrive Guitar Effects Pedal is easy. First, make sure you have a 9V DC (center negative polarity) power supply with at least 150mA of available current. You can also use the 9V battery, just open the magnetically latched hinged door. Turn on the pedal and start adjusting the knobs. The LED backlit knobs make it easy to see what you're doing. Use the 'A' and 'B' overdrive voicings to get different sounds. You can go from a little edge to a thick overdrive. And if you want to change the tone, use the flexible tone controls. When you play, you can clean up the sound with your guitar's volume control, just like you would with a Fender amplifier.
For maintenance, keep the pedal clean. Don't expose it to extreme heat or cold. If you're not using the battery for a long time, take it out to avoid damage. That's it, enjoy making great music with your Fender pedal!
