It features a maximum delay time of 800ms, which is more than enough for most musical applications. The pedal also has a built-in modulation effect that can be used to create chorus, flanger, and vibrato sounds. The DD-3 has a simple and intuitive interface, with three knobs that control the delay time, feedback, and effect level. It is built with high-quality components and is designed to withstand the rigors of touring and live performance.

Precautions When Connecting

To prevent malfunction and equipment failure, always turn down the volume, and turn off all the units before making any connections.
Once the connections have been completed, turn on power to your various devices in the order specified. By turning on devices in the wrong order, you risk causing malfunction and/or damage to speakers and other devices.
- When powering up: Turn on the power to your guitar amp last.
- When powering down: Turn off the power to your guitar amp first.
Before turning the unit on/off, always be sure to turn the volume down. Even with the volume turned down, you might hear some sound when switching the unit on/off. However, this is normal and does not indicate a malfunction.

Operating the Unit

DELAY (ECHO) EFFECT

After connecting all the cords required, set all the knobs on the panel as illustrated.
When the CHECK Indicator lights up by pressing the Pedal Switch down. Delay Effect is ON, and if goes out, Delay Effect is OFF.
This indicator serves as Battery Check Indicator as well. The battery should be replaced with a new one when the indicator lights only dimly or fails to light up.
Select the range of delay time with the MODE knob, and then adjust the Delay Time by rotating the D.TIME knob.
- High-frequency input signal can cause beat notes, making Delay sound muddy. Slight counterclockwise rotation of D. TIME will decrease beats.
Adjust the repetition time by setting the Feedback knob to a proper position.
- If this knob is set too high, oscillation may occur.
Adjust the output level of delay sound.
- Turning the knob to MAX makes the level of delay sound equivalent to the direct sound.
- When this knob is set to MIN in stereo mode, the delay sound is not output through the OUTPUT jack.

HOLD EFFECT

After connecting all the cords required, set the all knobs on the panel as illustrated.
- Feedback Effect does not works with Hold effect ON.
When the Check Indicator lights up by pressing the Pedal Switch down, Hold is ON. If it goes out by releasing the Pedal Switch, Hold is OFF (Normal).
- When you press the Pedal Switch down after playing some phrases, the last sound played will take on the Hold effect.
- The Pedal Switch works as long as the pedal is held down.
The delay time knob adjust the Hold Time (200 ms to 800 ms). When you rotate this knob while the hold sound is heard, its pitch changes; rotating it clockwise lowers the pitch and counterclockwise raises it.

Use of Battery

A battery was installed in the unit before it left the factory. The life of this battery may be limited, however, since its primary purpose was to enable testing.
If operating this unit on battery, please use alkaline battery.
If you handle batteries improperly, you risk explosion and fluid leakage. Make sure that you carefully observe all of the items related to batteries that are listed in “USING THE UNIT SAFELY” and “IMPORTANT NOTES” (supplied on a separate sheet).
When operating on battery power only, the unit’s indicator will become dim when battery power gets too low. Replace the battery as soon as possible.
Batteries should always be installed or replaced before connecting any other devices. This way, you can prevent malfunction and damage.

Setup Guide

To set up the BOSS DD-3 Digital Delay pedal, follow these steps:

Plug your instrument into the input jack of the pedal.
Connect the output jack of the pedal to your amplifier or other effects pedals.
Turn on the pedal using the power switch.

Changing the Battery

Remove the old 9 V Battery battery from the battery housing, and remove the snap cord connected to it.
Connect the snap cord to the new battery, and place the battery inside the battery housing.
- Be sure to carefully observe the battery’s polarity (+ versus -).
Slip the coil spring onto the spring base on the back of the pedal, and then close the pedal.
- Carefully avoid getting the snap cord caught in the pedal, coil spring, and battery housing.
Finally, insert the thumbscrew into the BOSS DD-3 Digital Delay guide bush hole and fasten it securely.
