Setup
Power Supply Connection:
The FLAMMA FC20 requires a 9V DC power supply with a center-negative polarity and a current rating of at least 300mA. The included power supply meets these specifications.
- Connect the barrel connector of the 9V power supply to the DC IN jack on the pedal.
- Plug the power supply into a standard AC wall outlet.

Connecting to Your Audio Setup:
- Connect your guitar to the Input Jack of the FC20 pedal using a standard 1/4-inch instrument cable.
- Connect the Output Jack of the FC20 pedal to your amplifier's input (or the input of the next pedal in your signal chain) using another 1/4-inch instrument cable.
- Ensure all connections are secure before powering on your amplifier.
Operating Instructions
Basic Operation:
- After connecting the pedal as described in the Setup section, ensure your amplifier is on and set to a clean channel for best results.
- Press the footswitch to engage the distortion effect. The LED indicator will illuminate when the effect is active. Press again to bypass the effect.
- Adjust the GAIN knob to control the amount of distortion. Start with a lower setting and gradually increase to find your desired level of saturation.
- Use the VOLUME knob to set the overall output level of the pedal. This allows you to match the volume with your bypassed signal or boost it for solos.
- Adjust the TONE knob to shape the frequency response of the distorted sound. Turning it clockwise will make the sound brighter, while turning it counter-clockwise will make it darker.
Tips for Optimal Tone:
- Experiment with different combinations of GAIN, VOLUME, and TONE settings to discover a wide range of distortion sounds.
- The FC20 works well with both single-coil and humbucker pickups. Adjust the GAIN accordingly.
- Placing the FC20 early in your signal chain (before modulation or time-based effects) typically yields the best results for distortion pedals.
Maintenance
- Cleaning: Use a soft, dry cloth to clean the pedal's exterior. Do not use abrasive cleaners, solvents, or waxes.
- Storage: When not in use for extended periods, disconnect the power supply and store the pedal in a cool, dry place away from direct sunlight and extreme temperatures.
- Power Supply: Always use the original or a compatible 9V DC center-negative power supply with at least 300mA current. Using an incorrect power supply can damage the unit.
- Connections: Periodically check all cable connections for wear and tear. Replace damaged cables to ensure optimal signal integrity.
