• DECAY Knob: Adjusts the length of the reverb tail. Turn clockwise for longer decay, counter-clockwise for shorter decay.
• MIX Knob: Controls the blend between the dry (unaffected) signal and the wet (effected) signal. Turn clockwise for more reverb effect, counter-clockwise for less.
• Type Selector Knob: A 9-position rotary switch to select one of the nine available reverb types.
• IN Jack: 1/4" mono input jack for connecting your guitar or other instrument.
• OUT Jack: 1/4" mono output jack for connecting to an amplifier or other effects pedal.
• 9V DC Power Input: Connects to a 9V DC power adapter (negative center).
• Footswitch: Toggles the effect on/off. Features true bypass for preserving your guitar's tone when the effect is disengaged.
• LED Indicator: Illuminates when the effect is active.

5. Setup

1. Ensure your amplifier is turned off or its volume is set to minimum.
2. Connect your guitar to the IN jack of the M-VAVE DIG REVERB pedal using a standard 1/4" instrument cable.
3. Connect the OUT jack of the M-VAVE DIG REVERB pedal to your amplifier's input (or the input of the next pedal in your signal chain) using another 1/4" instrument cable.
4. Connect a DC 9V power adapter (negative center) to the 9V DC power input jack on the pedal.
5. Once all connections are secure, you may power on your amplifier and adjust its volume.

6. Operating

Engaging the Effect

Press the footswitch to toggle the reverb effect on or off. The LED indicator will illuminate when the effect is active.

Selecting Reverb Types

Rotate the Type Selector Knob to choose from the 9 available reverb algorithms:

• HALL: Simulates the spacious and resonant acoustics of a large concert hall.
• ROOM: Emulates the natural reverberation of a smaller, more intimate room.
• PLATE: Recreates the classic bright and dense sound of a plate reverb unit.
• ECHO: Provides a distinct echo effect, adding repeats to your signal.
• TILE: Offers a unique, somewhat metallic or tiled room-like reverb character.
• FLANGER: Combines reverb with a flanger modulation effect for a swirling, ethereal sound.
• DUCKING: A reverb type where the reverb tail 'ducks' or lowers in volume when the dry signal is present, then swells back up when the dry signal fades.
• CHORUS: Integrates reverb with a chorus modulation effect, creating a thicker, shimmering sound.
• LOFI: Produces a degraded, vintage-style reverb sound with reduced fidelity.

Adjusting Reverb Parameters

• Use the DECAY knob to set the desired length of the reverb tail.
• Use the MIX knob to control the balance between your original guitar signal and the added reverb effect.

True Bypass

The M-VAVE DIG REVERB pedal features true bypass circuitry. This means that when the effect is disengaged, your guitar signal passes directly through the pedal without any electronic interference, preserving your original tone.

7. Maintenance

• Cleaning: Use a soft, dry cloth to clean the pedal's surface. Do not use abrasive cleaners or solvents.
• Storage: When not in use for extended periods, disconnect the power adapter and store the pedal in a dry, cool place away from direct sunlight.
• Connections: Periodically check all cable connections for wear and tear. Replace damaged cables to ensure optimal performance.

8. Troubleshooting

• No Sound:
  • Check all cable connections (guitar to IN, OUT to amp).
  • Ensure the 9V DC power adapter is correctly connected and functioning.
  • Verify that your guitar and amplifier are working correctly.
  • If using other pedals, temporarily remove them from the chain to isolate the issue.
• Poor Sound Quality / Excessive Noise:
  • Ensure the power adapter is a regulated 9V DC with negative center polarity. Unregulated power supplies can cause noise.
  • Check for faulty instrument cables.
  • Adjust the MIX knob to find a balanced level between dry and wet signals.
  • Test the pedal in a different power outlet to rule out electrical interference.
• LED Not Lighting Up:
  • Confirm the pedal is receiving power.
  • Press the footswitch to ensure the effect is engaged.
