Introduction
The M-VAVE Analog Delay Pedal is designed to provide warm and rich delay effects for guitar and bass. Featuring a pure analog circuit, it offers up to 600ms of delay time, true bypass functionality, and flexible power options. This manual provides essential information for setting up, operating, and maintaining your pedal to ensure optimal performance and longevity.
Setup
Follow these steps to connect your M-VAVE Analog Delay Pedal to your instrument and amplifier:
- Power Connection: Connect a 9V DC power adapter (center negative) to the DC9V input jack or use a USB charging cable to the USB port. Ensure the power source meets the pedal's requirements.
- Input Connection: Connect your guitar or bass to the IN jack on the right side of the pedal using a standard 1/4-inch instrument cable.
- Output Connection: Connect the OUT jack on the left side of the pedal to your amplifier or the next pedal in your signal chain using a standard 1/4-inch instrument cable.
- Activation: Press the footswitch to engage or disengage the delay effect. The true bypass design ensures your original signal remains unaffected when the pedal is off.

Operating Controls
The M-VAVE Analog Delay Pedal features six control knobs to shape your delay sound:
- LEVEL: Adjusts the overall output volume of the effect.
- HIGH: Controls the high-frequency content of the delayed signal.
- LOW: Controls the low-frequency content of the delayed signal.
- TIME: Sets the delay time, from a short slapback to a maximum of 600ms.
- F.B.ACK (Feedback): Determines the number of delay repeats. Turning it clockwise increases the repeats.
- MIX: Blends the wet (effected) signal with the dry (original) signal.
