Introduction
The Moskyaudio Mini Loop Box is a compact guitar effect pedal designed to provide true bypass functionality and channel selection for your effects chain. This device allows you to integrate a group of effects pedals into a single switchable loop, ensuring that your core guitar tone remains unaffected when the looped effects are disengaged. It is important to note that this pedal functions as an effects loop switcher and is not a recording looper pedal.
Key features include:
- True bypass design to preserve signal integrity.
- Dedicated SEND and RETURN jacks for integrating external effects.
- Footswitch for instant channel selection between direct signal and effects loop.
- LED indicator to display the active status.
- Durable zinc-aluminum alloy casing for road-worthiness.
Safety Information
Please read and understand the following safety precautions before operating the device:
- Power Supply: Use only a regulated DC 9V power adapter with center-negative polarity. Incorrect voltage or polarity can damage the unit and void the warranty. This pedal does not support battery power.
- Environment: Do not expose the pedal to water, moisture, excessive heat, or direct sunlight. Operate in a clean, dry environment.
- Handling: While constructed from durable materials, avoid dropping or subjecting the pedal to severe impacts.
- Cleaning: Disconnect power before cleaning. Use a soft, dry cloth. Do not use liquid cleaners.
- Servicing: Do not attempt to open or service the unit yourself. Refer all servicing to qualified personnel.
Setup
Follow these steps to connect your Mini Loop Box:
- Power Connection: Connect a standard DC 9V center-negative power adapter (not included) to the power input jack on the side of the pedal. Ensure the power supply meets the specified requirements.
- Input Connection: Connect your guitar or the output of a preceding pedal to the IN jack on the right side of the Mini Loop Box using a standard 1/4-inch instrument cable.
- Output Connection: Connect the OUT jack on the left side of the Mini Loop Box to your amplifier's input or the input of the next pedal in your signal chain using a standard 1/4-inch instrument cable.
- Effects Loop Connection:
- Connect the SEND jack (top left) to the input of the first effect pedal you wish to include in the loop.
- Connect the output of the last effect pedal in your loop to the RETURN jack (bottom left).

Operating Instructions
The Mini Loop Box offers straightforward operation for managing your effects chain:
- Engaging/Disengaging the Loop: Press the footswitch to toggle between the direct signal path and the effects loop.
- When the effects loop is engaged, your signal will pass through the pedals connected to the SEND and RETURN jacks.
- When the effects loop is disengaged, your signal will bypass the SEND/RETURN loop entirely, passing directly from the IN jack to the OUT jack. This is the true bypass function, preserving your dry signal.
- LED Indicator: The LED lights indicate the active status of the pedal. When the LED is lit, the effects loop is engaged. When the LED is off, the signal is in true bypass mode.
This functionality is particularly useful for pedals that do not have true bypass themselves, or for switching multiple effects in and out of your signal path with a single stomp.

Maintenance
Proper care will ensure the longevity of your Mini Loop Box:
- Cleaning: Use a soft, dry cloth to wipe the exterior of the pedal. Avoid abrasive cleaners, solvents, or any liquids that could seep into the internal components.
- Storage: When not in use for extended periods, store the pedal in a dry, temperate environment, away from direct sunlight and extreme temperatures.
- Connections: Periodically check all cable connections for tightness and ensure cables are not frayed or damaged.
Troubleshooting
If you encounter issues, refer to the following troubleshooting guide:
- No Sound:
- Ensure the power adapter is correctly connected and providing DC 9V center-negative power.
- Verify all 1/4-inch instrument cables are securely plugged into the correct IN, OUT, SEND, and RETURN jacks.
- Check the functionality of your guitar, amplifier, and other pedals in the chain independently.
- Confirm the footswitch is engaged (LED lit) if you expect sound from the effects loop, or disengaged (LED off) for the direct signal.
- Hum or Noise:
- Ensure you are using a regulated power supply. Unregulated power supplies can introduce noise.
- Check all cables for proper shielding and damage.
- Isolate the Mini Loop Box by connecting it directly to your guitar and amp. If the noise disappears, the issue may be with another pedal or cable in your setup.
- LED Not Lighting:
- Confirm the power adapter is connected and functioning.
- Ensure the power supply meets the DC 9V center-negative specification.
