Boss FZ-5 Owner’s Manual

The Boss FZ-5 can be powered using a 9V DC power adapter or a 9V battery. Ensure that the adapter is a center-negative type to prevent damage.
Connect your guitar to the input jack and the output jack to your amplifier or the next pedal in your chain. Use standard 1/4-inch instrument cables for the connections.
The Boss FZ-5 features three modes: Fuzz Face, Maestro FZ-1A, and Octavia. These modes can be selected using the mode knob on the pedal.
Use the mode knob to switch between Fuzz Face, Maestro FZ-1A, and Octavia settings. Rotate the knob to select the desired fuzz type for your sound.
Check all cable connections and ensure that the pedal is powered. Verify that the battery or power adapter is functional and properly connected.
Use a soft, dry cloth to clean the exterior of the pedal. Avoid using any solvents or abrasive materials that could damage the finish.
Store the pedal in a cool, dry place. Remove the battery if the pedal will not be used for an extended period to prevent leakage.
Use the 'Fuzz' knob to control the intensity of the effect. Turn it clockwise for more fuzz and counterclockwise for less.
Yes, the Boss FZ-5 can be used with a bass guitar, though the tonal characteristics may differ from those with a standard guitar. Experiment with settings for best results.
Check for ground loops or interference from other devices. Ensure cables are in good condition and try isolating the pedal from other electronic equipment.
