Control Knobs:

LEVEL: Adjusts the output level of the delayed signal. Turn clockwise to increase the delay volume.
REPEATS: Controls the number of delay repetitions (feedback). From a single echo to infinite repeats.
TIME: Sets the delay time, from very short slap-back echoes to long, ambient delays.
MODE: Selects one of the seven available delay types:
1. 1-10-250 MS: Short delay times, ideal for slap-back and subtle echoes.
2. 2-250-1 SEC: Medium delay times, suitable for rhythmic delays.
3. 3-1-4 SEC: Long delay times, for atmospheric and ambient effects.
4. 4-TAPE: Simulates the warm, decaying sound of vintage tape echo units.
5. 5-MOD DELAY: Adds modulation (chorus/flange) to the delayed signal for swirling effects.
6. 6-REVERSE: Plays the delayed signal backward, creating unique soundscapes.
7. 7-LOOP: Enables a short looping function for creating sound-on-sound layers.

Jacks:

IN: 1/4-inch input jack for connecting your guitar or other instrument.
OUT 1 (MONO): 1/4-inch output jack for mono signal. Connect to your amplifier or next pedal in the chain.
OUT 2: 1/4-inch output jack for stereo signal. Use with OUT 1 for stereo effects or with a second amplifier.
9V DC Input: For connecting an optional 9V DC power adapter (center negative).

Footswitch:

Engages or bypasses the effect. Also used for Tap Tempo functionality (refer to Operation section).

Setup

Powering the Pedal:
- The DigiDelay pedal can be powered by a single 9V battery (included) or an optional 9V DC power adapter (center negative).
- To install a battery, unscrew the four screws on the bottom plate and carefully remove it. Insert a 9V battery into the clip and replace the plate.
- If using a power adapter, connect it to the 9V DC input jack.
Connecting to Your Rig:
- Connect your guitar to the IN jack of the DigiDelay pedal using a standard 1/4-inch instrument cable.
- For mono operation, connect the OUT 1 (MONO) jack to your amplifier's input or the next pedal in your signal chain.
- For stereo operation, connect OUT 1 (MONO) to one amplifier (or channel) and OUT 2 to a second amplifier (or channel).
Initial Settings:
- Before turning on your amplifier, set the LEVEL, REPEATS, and TIME knobs to their minimum positions (fully counter-clockwise).
- Select your desired MODE.
- Turn on your amplifier and then gradually adjust the pedal's controls to achieve your desired sound.

Operation

Operating the DigiDelay pedal involves selecting the delay type and adjusting the parameters to shape your sound.

Engaging the Effect:

Press the footswitch once to engage the delay effect. The LED indicator will illuminate. Press it again to bypass the effect; the LED will turn off.

Adjusting Delay Parameters:

LEVEL: Start with the LEVEL knob at a low setting and gradually increase it until the delayed signal blends well with your dry signal. Avoid setting it too high, which can lead to unwanted volume boosts or feedback.
REPEATS: Experiment with the REPEATS knob to control the decay of the echoes. Lower settings produce fewer repeats, while higher settings create longer, more sustained echoes. At maximum, the pedal can self-oscillate, creating infinite feedback.
TIME: Rotate the TIME knob to set the duration between repeats. This knob works in conjunction with the selected MODE to determine the overall delay range.
MODE: Turn the MODE knob to select from the seven distinct delay algorithms. Each mode offers a unique character and range of delay times. Refer to the "Controls and Connections" section for a description of each mode.

Tap Tempo:

The Tap Tempo feature allows you to set the delay time by tapping the footswitch. To use Tap Tempo:

Ensure the pedal is engaged (LED on).
Tap the footswitch two or more times in rhythm with the desired tempo. The pedal will calculate the delay time based on your taps.
The Tap Tempo feature is active in most delay modes, providing precise synchronization for live performance.

Maintenance

Battery Replacement: When the LED indicator dims or the pedal's performance degrades, it's time to replace the 9V battery. Always use a fresh alkaline battery for optimal performance.
Cleaning: Clean the pedal's exterior with a soft, dry cloth. Do not use abrasive cleaners or solvents, as they may damage the finish or internal components.
Storage: When not in use for extended periods, remove the battery to prevent leakage. Store the pedal in a cool, dry place away from direct sunlight and extreme temperatures.
Connections: Periodically check all cable connections for tightness and ensure cables are not frayed or damaged.

Troubleshooting

Problem	Possible Cause	Solution
No sound or weak signal when pedal is engaged.	Battery is dead or low. Power adapter is not connected or faulty. Cables are faulty or incorrectly connected. LEVEL knob is set too low.	Replace the 9V battery. Ensure power adapter is securely connected and functional. Check all instrument cables; try different cables. Verify correct input/output connections. Increase the LEVEL knob setting.
Unwanted noise or hum.	Poor quality power supply. Ground loop issue. Interference from other electronic devices.	Use a high-quality, regulated 9V DC power supply. Ensure all equipment is on the same power circuit or use a power conditioner. Move the pedal away from power transformers or other noisy electronics.
Delay effect is not noticeable.	LEVEL, REPEATS, or TIME knobs set too low. Pedal is in bypass mode.	Adjust LEVEL, REPEATS, and TIME knobs to higher settings. Press the footswitch to engage the effect (LED should be on).
