Released in 1983 at the dawn of the digital effects era, the Roland SDE-3000 is a hallowed icon among fans of classic gear. With its highly musical character, long delay times, and ability to store and recall presets, this rackmount legend went on to become the prime delay machine for the world's finest touring guitarists, session musicians, and engineers of the time, and its special sound is still revered forty years later.

The SDE-3000D brings you not one but two authentic reproductions of the much-loved SDE-3000 in a floor-based pedal. Fully independent delays, flexible internal routing, and expanded I/O offer modern versatility for all types of mono and stereo rigs. Modulation and tone-shaping capabilities have also been enhanced, and there are 100 memories for storing favorite setups. And with a wealth of onboard and external control options - including deep MIDI support - you can integrate this inspiring vintage voice with any stage or studio setup.


• Faithful floor-based reproduction of the legendary Roland SDE-3000 rackmount digital delay from the 1980s
• Classic warm digital delay sound with extended features for modern rigs
• Distinctive retro display and panel controls based on the original SDE-3000
• Includes two full-featured delays, each with independent parameters, mono/stereo modulation, and panning
• Widely adjustable delay time with two range settings: 0-1500 ms and 0-3000 ms
• Characterful modulation inspired by the original circuit design
• Phase switches for the primary delay and delay feedback loop
• Adjustable low-cut and high-cut filters for shaping delay feedback sounds
• Two inputs and two outputs for dual mono, wet/dry, or stereo setups
• Selectable series or parallel operation for the two delays
• Save and recall sounds with 100 memories
• Assignable onboard footswitch control for tap tempo, hold, and more
• Jacks for extended operation with up to four footswitches, two expression pedals, or the GA-FC/GA-FC EX foot controller
• MIDI I/O on space-saving mini TRS jacks

Authentic Details, Modern Enhancements
The SDE-3000D includes nearly every parameter from the SDE-3000, accessed via a retro interface derived from the vintage hardware. Two selectable delay ranges offer different frequency characteristics, vital elements in the original's appealing sound. The unique tonal color of the SDE-3000's external feedback loop circuit has been replicated as well, and it's possible to turn this coloration off or internally process the feedback loop with a powerful EQ. You also get 100 memories - up from the original's eight - plus carryover when switching sounds.

Masterful Modulation
The modulation circuit in the SDE-3000 also contributes to the effect's distinctive sound. Along with basic depth and rate controls, it's possible to independently switch the phase of the initial delay and the delay feedback loop, which influences the way the modulation reacts. The original analog LFO behavior has been faithfully reproduced in the SDE-3000D, and there's now a sine wave option in addition to the original triangle wave. The SDE-3000D also provides even more control over the delay phase settings for a broader range of sounds.

Modern Compact Power
With 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 a large selection of assignable targets to choose from, delivering deep real-time control that reaches far beyond the capabilities of the original SDE-3000.
