It visually represents modulation settings and any engaged effects, like shimmer or reverse. Preset numbers are clearly displayed, alongside indicators for tap tempo status and external control via MIDI.
The screen also shows parameter values when adjusting knobs, offering real-time feedback. Understanding the screen’s layout and indicators is essential for navigating the DD-20’s extensive features and customizing delay sounds effectively.
Basic Operation
Getting started with the DD-20 is straightforward. Power on the pedal and connect it to your instrument and amplifier. The pedal defaults to a standard digital delay mode upon startup. Use the [DELAY TIME] knob to adjust the echo time, [FEEDBACK] to control the number of repeats, and [LEVEL] to set the delay’s volume.
Experiment with different delay modes by pressing the mode selection buttons. The footswitch toggles the delay effect on or off. Mastering these core controls allows for immediate sound shaping and exploration of the DD-20’s sonic capabilities.
Turning the DD-20 On/Off
Powering up the BOSS DD-20 is simple. Connect the included DC power adapter to the pedal’s DC IN jack and a suitable power outlet. Alternatively, you can power the DD-20 with six AA batteries. To turn the pedal on, press the footswitch once; the indicator light will illuminate. Pressing the footswitch again disables the delay effect, indicated by the light extinguishing.
The DD-20 retains its settings even when powered off, allowing you to resume your sound instantly. Ensure proper power connection for stable operation and to avoid unexpected interruptions during performance.
Selecting Delay Modes
The BOSS DD-20 boasts a diverse range of delay modes, accessible via the MODE knob. Rotate the knob to cycle through Standard, Tape, Analog, Digital, Reverse, and Looper modes, each offering a unique sonic character. Experiment with these modes to discover the perfect delay sound for your musical style.
Each mode provides distinct tonal qualities, from the warm saturation of Tape mode to the pristine clarity of Digital. The Looper mode allows for recording and playback of phrases, expanding creative possibilities. Explore each setting to unlock the DD-20’s full potential.
Adjusting Delay Time, Feedback, and Level
The DD-20’s core parameters – Delay Time, Feedback, and Level – are controlled via dedicated knobs. Delay Time dictates the interval between repetitions, adjustable from subtle echoes to long, atmospheric delays. Feedback determines how many times the delayed signal repeats, creating anything from a single repeat to self-oscillation.
Level controls the volume of the delayed signal relative to the direct signal. Careful adjustment of these parameters is crucial for achieving the desired delay effect. Experimentation is key to finding the sweet spot for your sound, blending the delay seamlessly with your instrument.
Advanced Features
The BOSS DD-20 extends beyond basic delay, offering advanced features for sonic exploration. Utilize the Expression Pedal for real-time control over delay parameters, adding dynamic sweeps and textures. Tap Tempo allows for precise delay time synchronization, perfect for playing in time with a band or backing track.
Preset saving and loading enables quick recall of customized delay settings. Furthermore, MIDI control provides seamless integration with other gear, expanding creative possibilities. These features unlock a world of sound design, transforming the DD-20 into a versatile delay powerhouse.
Using the Expression Pedal
The BOSS DD-20’s expression pedal input unlocks dynamic control over delay parameters. Assign any parameter – delay time, feedback, level, or modulation depth – to the pedal for real-time manipulation. This allows for expressive swells, rhythmic gating effects, and evolving soundscapes.
Connect a compatible expression pedal to the rear panel. Configure the assignment via the pedal assign menu. Experiment with different parameter assignments to discover unique sonic textures. The expression pedal transforms the DD-20 from a static effect into a highly interactive instrument.
Tap Tempo Functionality
The DD-20’s tap tempo feature provides a convenient method for setting delay times manually. Simply press the tap tempo footswitch (or a connected external switch) in time with the desired tempo. The delay time will synchronize to your rhythmic input, ensuring precise timing. This is particularly useful for live performance where tempos may vary.
Tap tempo overrides previously set delay times. Hold the tap tempo switch to enter tap tempo mode, allowing for continuous tempo adjustments. Experiment with dotted eighth note and triplet subdivisions for complex rhythmic effects.
Saving and Loading Presets
The DD-20 allows you to save and recall custom delay settings as presets, streamlining your workflow. To save a preset, adjust the delay parameters to your desired settings, then press the ‘Write’ button and select a memory location (1-99). Confirm the save to store the preset.
Loading presets is equally straightforward. Press the ‘Read’ button, then select the desired preset number using the value dial. The DD-20 instantly recalls the saved settings. Regularly backing up your presets is recommended to prevent data loss.
External Control (MIDI)
The BOSS DD-20 offers extensive MIDI control for seamless integration with your existing setup. Via a standard 5-pin MIDI connector, you can control various parameters, including preset selection, delay time, feedback, and level, from an external MIDI controller or sequencer.
MIDI implementation charts detail specific control change (CC) numbers for each parameter. This allows for precise and automated control over your delay effects. The DD-20 can also transmit MIDI data, enabling it to synchronize with other MIDI devices in your rig.
Troubleshooting Common Issues
Encountering problems? This section addresses frequent issues. Power Issues: Ensure the correct power supply is used (9V DC, center-negative). Check the DC-in jack for secure connection. Sound Quality Problems: Verify cable connections to your instrument and amplifier. Adjust input gain and output level. Experiment with different delay modes.
Preset Saving/Loading Errors: Confirm sufficient memory is available. Try re-saving the preset. If issues persist, consider a firmware update. Regularly check for updates on the BOSS website to maintain optimal performance and resolve potential bugs.
Power Issues
If the DD-20 fails to power on, first verify the power supply. Ensure you are using a 9V DC power adapter with a center-negative polarity – this is crucial. Check the DC-in jack on the pedal itself; confirm the adapter is firmly and securely connected. A loose connection is a common cause of power failure;
Also, test the adapter with another compatible device to rule out a faulty power supply. If using batteries, ensure they are fresh and correctly installed. A depleted battery will obviously prevent operation. Finally, inspect the power cable for any visible damage.
Sound Quality Problems
If experiencing distorted or absent sound, begin by checking all cable connections – input, output, and any expression pedal connections; Ensure cables are securely plugged into both the DD-20 and your amplifier/instrument. Verify the input level on the DD-20 isn’t set too high, causing clipping. Experiment with the direct level and delay level knobs to find a balanced mix.
Additionally, confirm your amplifier’s settings are appropriate and not contributing to the issue. Try a different instrument cable to rule out a faulty cable. If the problem persists, reset the DD-20 to factory settings.
Preset Saving/Loading Errors
Encountering difficulties saving or loading presets? First, verify sufficient memory is available on the DD-20. A full memory bank will prevent new saves. If saving fails, try saving to a different preset location. For loading errors, ensure the preset isn’t corrupted – attempt loading a known-good preset to confirm functionality.
Consider performing a power cycle of the DD-20; this can resolve temporary glitches. If errors persist, a firmware update might address underlying software issues. Back up important presets before updating. Contact BOSS support if problems continue, providing details about the error message and steps taken.
Firmware Updates
Regular firmware updates are crucial for maintaining optimal performance and accessing new features on your BOSS DD-20. These updates often address bugs, improve stability, and enhance the overall user experience. Before proceeding, ensure a stable power supply to prevent interruptions during the update process.
