BOSS - SDE-3000D

The Rebirth of A Vintage Digital Delay LegendIntroduced in 1983 at the rise of the digital effects era, the Roland SDE-3000 has become an icon to fans of classic gear. Featuring highly musical character, long delay times, and ability to store and recall presets, this rackmount legend went on to become the must-have delay machine for the world’s finest touring guitarists, session musicians, and engineers of the time. Its unique sound is still revered four decades later.
The SDE-3000D gives you not one but two authentic reproductions of the much-loved SDE-3000 in a floor-based pedal. Entirely independent delays, flexible internal routing, and expanded I/O provide modern versatility for all types of mono and stereo rigs. Enhanced modulation and tone-shaping capabilities and 100 memories for storing favourite setups. And with a wide range of onboard and external control options, such deep MIDI support, you can integrate this inspiring vintage voice with any stage or studio setup.

Retro Digital Magic

Truly inspirationalMusicians and engineers lean towards certain classic effects as they make any sound better, and the SDE-3000 is a fine example of that. Many elements made it highly expressive with live instruments, including ultra-wide dynamic range, adjustable delay phase, rich modulation, and multiple seconds of clear but warm delay tone.
The SDE-3000’s voice became an integral part of music in the 1980s and 1990s and remains a source of inspiration for tone seekers and effect builders everywhere. With the SDE-3000D, you can now access the authentic delay sounds used to produce some of the most legendary tracks ever made.
Faithful Sound Reproduction

Intelligent digital processingIn comparison to other clear, precise sounding digital delays, the SDE-3000 stood out from the crowd with its stunning warm sound and inviting musicality. This was the result of intelligent and complex internal digital processing paired with nonlinear behaviours from the supporting analogue circuitry.
These behaviours included variable frequency response in the preamp based on input gain, magnetic saturation in the anti-alias filter, and growing modulation produced by the components of the time. BOSS deeply analyzed these many factors when designing the SDE-3000D, bringing the complete character of this time-honored classic alive for the modern era.
Authentic Details, Modern Enhancements

More memoriesThe SDE-3000D features almost every parameter from the SDE-3000, accessed using a retro interface taken from the vintage hardware. Two selectable delay ranges offer different frequency characteristics, crucial elements in the original’s appealing sound.
The unique tonal colour of the SDE-3000’s external feedback loop circuit has been replicated too, you can also turn this colouration off or internally process the feedback loop with a powerful EQ. You also get 100 memories, whereas the original had eight, plus carryover when switching sounds.
Masterful Modulation

More SoundsThe modulation circuit in the SDE-3000 is also responsible to the effect’s distinctive sound. Together with basic depth and rate controls, you can independently switch the phase of the initial delay and the delay feedback loop, which influences the way the modulation reacts.
The original analogue LFO behaviour has been faithfully reproduced in the SDE-3000D, and there’s now a sine wave option in addition to the original triangle wave. Even more control over the delay phase settings has been provided for a wider range of sounds.
Two SDE-3000s In One Pedal

Run in seriesWhile the original SDE-3000 was mono, the SDE-3000D gives you two discrete delays with independent parameters and mono or stereo modulation on each. Run the delays in parallel and pan them for ever-evolving stereo colours.
Alternatively, you can chain them in series to create complex rhythms and reverb-like depth. With the flexible audio I/O, you can route the effects for wide stereo operation, send each delay to its own output, or split effect and unprocessed sounds for wet/dry setups.
Modern Compact Power

Greater versatilityThanks to its pedal-based design and expanded control options, the SDE-3000D offers much greater versatility than its rackmount inspiration. Three onboard footswitches provide instant control of memory selection, tap tempo, delay hold, momentary effect engagement, and more.
Two control jacks allow you to connect up to four footswitches, two expression pedals, or a GA-FC/GA-FC EX for external operation, and TRS MIDI I/O is also included. There’s also a large selection of assignable targets to choose from, delivering deep real-time control that reaches much further than the capabilities of the original SDE-3000.
