4.3. Connecting Effect Loops
The JF-24 features two independent effect loops, Line A and Line B. To connect pedals to a loop:
- Connect the SEND A jack to the input of the first pedal in your Line A effect chain.
- Connect the output of the last pedal in your Line A effect chain to the RETURN A jack.
- Repeat the process for Line B using the SEND B and RETURN B jacks.

5. Operating Modes
The JF-24 offers six looping modes, selectable via the LINE Mode Selection Control Knob. These modes allow for various configurations of your effect loops:
- 1. A/B: Switches between Line Loop A and Line Loop B.
- 2. A/BYPASS: Switches between Line Loop A and a bypassed signal (dry guitar signal).
- 3. B/BYPASS: Switches between Line Loop B and a bypassed signal (dry guitar signal).
- 4. A/B/BYPASS: Cycles through Line Loop A, Line Loop B, and a bypassed signal.
- 5. A+B/BYPASS: Switches between both Line Loop A and Line Loop B engaged simultaneously, and a bypassed signal.
- 6. A/B/OUT SELECT: This mode allows you to use the SEND A, SEND B, and OUTPUT jacks as three independent outputs. Your guitar signal goes into the INPUT, and you can switch between sending it to SEND A, SEND B, or the main OUTPUT. This is useful for routing your signal to different amplifiers (e.g., guitar amp, bass amp, tuner) or other destinations. In this mode, the RETURN A and RETURN B jacks are not used for effect loops.

8. Troubleshooting
- No Sound: Ensure all cables are securely connected to the correct input/output jacks. Verify the power adapter is properly connected and supplying power. Check the volume levels on your guitar, pedal, and amplifier.
- Unexpected Noise: Ensure all connections are tight. Use a high-quality, isolated power adapter to minimize noise. If using multiple pedals, ensure they are properly grounded.
- Pedal Not Engaging: Check the selected operating mode. Some modes may require specific configurations for the footswitch to activate loops.
- Tone Loss: If you experience tone loss when a pedal is off but still in a loop, consider placing that pedal in one of the JF-24's loops and using the selector to bypass it completely when not in use.
9. Maintenance
To ensure the longevity and optimal performance of your JOYO Orthros Selector JF-24:
- Keep the pedal clean and free from dust and debris. Use a soft, dry cloth for cleaning.
- Avoid exposing the pedal to extreme temperatures, humidity, or direct sunlight.
- Do not attempt to disassemble or modify the pedal, as this may void the warranty and cause damage.
- Always use the correct power supply (DC 9V, center negative) to prevent damage.
