4. Setup
Follow these steps to set up your M VAVE ABY Line Selector AB Switch:
- Power Connection: Connect a DC9V (center negative) power adapter to the DC IN jack or a USB 5V power source to the USB jack. Note: The pedal can function without external power if LED indication is not required.
- Instrument/Source Connection:
- Scenario 1 (Two Inputs to One Output): Connect your first instrument (e.g., Guitar 1) to the 'A' jack and your second instrument (e.g., Guitar 2) to the 'B' jack. Connect your amplifier or desired output device to the 'C' jack.
- Scenario 2 (One Input to Two Outputs): Connect your instrument (e.g., Guitar) to the 'C' jack. Connect your first amplifier/output device to the 'A' jack and your second amplifier/output device to the 'B' jack.
- Cable Management: Ensure all cables are securely connected and routed to prevent tripping hazards or accidental disconnections.

5. Operating Instructions
The M VAVE ABY pedal offers flexible signal routing. Understand its modes and functions:
5.1. Signal Flow Direction
The ABY pedal supports dual-direction signal flow:
- A/B to C: Route signals from either A or B (or both) to C. Ideal for switching between two instruments into one amplifier.
- C to A/B: Route a signal from C to either A or B (or both). Ideal for sending one instrument's signal to two different amplifiers or effects chains.

5.2. Mode Select Switch
Use the small toggle switch to select the desired output mode:
- A/B Mode: In this mode, the footswitch toggles between channel A and channel B. Only one channel will be active at a time.
- A&B Mode: In this mode, the footswitch toggles between channel A and both channels A and B simultaneously. This allows you to combine signals or send a signal to both outputs.
5.3. Footswitch Operation
Press the footswitch to switch between the active channels based on the selected mode. The true bypass design ensures that when the pedal is disengaged (or not powered for LED), your signal passes through without coloration.
5.4. LED Indicators
The LED provides visual feedback on the active channel(s):
- Red LED: Channel A is active.
- Green LED: Channel B is active.
- Yellow LED: Both Channel A and Channel B are active.

6. Maintenance
Proper care and maintenance will extend the life of your M VAVE ABY pedal:
- Cleaning: Use a soft, dry cloth to wipe down the pedal. Avoid abrasive cleaners, solvents, or excessive moisture, which can damage the finish or internal components.
- Storage: Store the pedal in a cool, dry place away from direct sunlight, extreme temperatures, and high humidity.
- Handling: Avoid dropping the pedal or subjecting it to strong impacts. While robust, excessive force can cause damage.
- Connections: Periodically check all cable connections for wear and tear. Replace damaged cables to ensure optimal performance and safety.
7. Troubleshooting
If you encounter issues with your M VAVE ABY pedal, refer to the following common troubleshooting steps:
- No Sound Output:
- Ensure all cables are securely connected to the correct input/output jacks.
- Check the Mode Select Switch position (A/B or A&B) and ensure the footswitch is set to the desired active channel.
- Test your instrument and amplifier independently to confirm they are working correctly.
- If using power, ensure the power supply meets the specifications (DC9V or USB5V) and is properly connected.
- LED Not Lighting Up:
- The pedal can operate without power (true bypass), but the LED indicators require power. Ensure a compatible power supply is connected and functioning.
- Verify the power supply's polarity (DC9V center negative).
- Signal Loss or Noise:
- Ensure you are using high-quality instrument cables.
- Check for any damaged cables or loose connections.
- Ensure the pedal is not placed too close to power supplies or other devices that might cause electromagnetic interference.
- Footswitch Not Responding:
- Ensure the footswitch is fully depressed.
- If the issue persists, contact customer support.
