Key Features:
- Compact mini housing.
- Classic silicon BC-108 transistor fuzz tone.
- Two-knob interface: Output and Fuzz.
- Buffer switch for improved compatibility with wah pedals and other effects.
- True bypass switching.
Setup
Follow these steps to connect your MXR Classic 108 Fuzz Mini to your guitar and amplifier:
- Power Connection: The pedal requires a 9-volt DC power adapter (not included). Connect the adapter to the power input jack located at the top of the pedal. Ensure the adapter is center-negative.
- Input Connection: Connect your guitar to the INPUT jack on the right side of the pedal using a standard 1/4-inch instrument cable.
- Output Connection: Connect the OUTPUT jack on the left side of the pedal to your amplifier or the next effect in your signal chain using another 1/4-inch instrument cable.
- Signal Chain Placement: The MXR Classic 108 Fuzz Mini can be placed at various points in your signal chain. For traditional fuzz tones, it is often placed early in the chain, before overdrive or distortion pedals. The buffer switch allows for greater flexibility in placement, especially when used with wah pedals.

Operating Instructions
The MXR Classic 108 Fuzz Mini features a straightforward control layout:

- OUTPUT Knob: Controls the overall output volume of the effect. Turn clockwise to increase volume, counter-clockwise to decrease.
- FUZZ Knob: Adjusts the intensity of the fuzz effect. Turn clockwise for more aggressive, saturated fuzz, and counter-clockwise for a milder fuzz.
- BUFFER Switch: This small switch located near the top of the pedal activates or deactivates the internal buffer. When the buffer is engaged, it helps maintain signal integrity and prevents impedance issues, particularly when the pedal is placed before other effects like wah pedals. Experiment with both settings to find what works best with your setup.
- Footswitch: Engages or bypasses the effect. When the effect is engaged, the LED indicator will illuminate. The pedal features true bypass, ensuring your signal remains unaffected when the pedal is disengaged.
Maintenance
- Cleaning: Use a soft, dry cloth to clean the pedal. Avoid abrasive cleaners or solvents.
- Storage: Store the pedal in a dry environment away from direct sunlight and extreme temperatures.
- Power: Always disconnect the power adapter when the pedal is not in use for extended periods.
Troubleshooting
- No Sound:
- Check all cable connections (guitar to input, output to amp).
- Ensure the 9V DC power adapter is correctly connected and functioning.
- Verify that the footswitch is engaged (LED illuminated).
- Weak or Distorted Sound (unintended):
- Check the power supply; insufficient power can cause poor performance.
- Adjust the OUTPUT and FUZZ knobs.
- Experiment with the BUFFER switch, especially if using other pedals in the chain.
- Excessive Noise:
- Ensure all cables are in good condition and properly shielded.
- Try a different power supply to rule out noise from the adapter.
- Fuzz pedals can be sensitive to placement in the signal chain and other electrical interference.
