One Control Minimal Series BJF Buffer Pedal with Phase Inversion Switch

1. Introduction

The One Control Minimal Series BJF Buffer Pedal is designed to maintain signal integrity across your guitar rig, especially with long cable runs or complex pedalboards. It prevents tone degradation by providing a strong, consistent signal. This model also features a phase inversion switch to correct potential phase issues within your setup.

2. Features

• High-quality buffer circuit designed by BJF.
• Eliminates signal loss and tone degradation over long cable runs.
• Integrated phase inversion switch for correcting polarity issues.
• Compact Minimal Series design for pedalboard efficiency.
• Robust construction for reliable performance.

3. Package Contents

Please ensure all items are present in the package:

• One Control Minimal Series BJF Buffer Pedal
• User Manual (this document)

Note: A 9V DC power supply (center negative) is required and sold separately.

4. Controls and Connections

The One Control Minimal Series BJF Buffer Pedal features straightforward controls for ease of use. While the images below depict a related "BJF Buffer Split" model, the general connection points for input, output, and power are similar.

4.1. Input Jack

Connect your instrument or the output of the preceding pedal in your signal chain to this jack. The buffer will process the signal from this point.

4.2. Output Jack

Connect this jack to your amplifier or the input of the next pedal in your signal chain. This is where the buffered signal exits the pedal.

4.3. DC 9V Input

Connect a standard 9V DC power supply (center negative) to this jack. The pedal requires external power to operate.

4.4. Phase Inversion Switch

This switch allows you to invert the phase of your signal. In some setups, especially when combining multiple effects or amplifiers, phase cancellations can occur, leading to a thin or weak sound. Flipping this switch can correct such issues, restoring fullness to your tone. Experiment with its position to find the optimal setting for your rig.

5. Setup

1. Ensure your amplifier and other audio equipment are turned off before making connections.
2. Connect your guitar or the output of your first pedal to the Input jack of the BJF Buffer.
3. Connect the Output jack of the BJF Buffer to your amplifier or the input of the next pedal in your signal chain.
4. Connect a 9V DC (center negative) power supply to the DC 9V Input jack.
5. Once all connections are secure, you may power on your amplifier and other equipment.

6. Operation

The BJF Buffer is designed for "always-on" operation. It does not have a footswitch to engage or bypass the buffering effect, as its primary purpose is to maintain signal integrity continuously.

• Buffering: Once powered, the pedal automatically buffers your signal, preventing high-frequency loss and maintaining clarity, especially with long cable runs or large pedalboards.
• Phase Inversion: If you experience a thin or hollow sound when combining your buffered signal with other effects or amplifiers, try flipping the Phase Inversion Switch. This often resolves phase cancellation issues and restores the full body of your tone. Listen carefully to determine the optimal setting for your specific setup.

7. Maintenance

• Cleaning: Use a soft, dry cloth to clean the pedal's exterior. Avoid abrasive cleaners or solvents.
• Storage: Store the pedal in a dry environment, away from extreme temperatures and direct sunlight.
• Power: Always use a regulated 9V DC (center negative) power supply to prevent damage to the unit.
• Connections: Periodically check all cable connections for wear and tear to ensure optimal signal transfer.

8. Troubleshooting

• No Sound:
  • Ensure the power supply is correctly connected and functioning.
  • Check all audio cables for proper connection and integrity.
  • Verify that your instrument and amplifier are working correctly.
• Poor Tone / Thin Sound:
  • If the sound is thin or hollow, try flipping the Phase Inversion Switch. This often resolves phase cancellation issues.
  • Ensure all cables are of good quality and not damaged.
  • Test the pedal in a simpler setup to isolate the issue.
• Noise / Hum:
  • Ensure you are using a high-quality, isolated 9V DC power supply.
  • Check for ground loops in your setup.
  • Move the pedal away from power transformers or other sources of electromagnetic interference.
