The delay that revolutionized modern rock and pop.

Introduced in 1982, the KORG SDD-3000 Digital Delay was popularized by U2 guitarist, The Edge, to forge one of the most identifiable guitar sounds in the history of rock. Far from a one-instrument-pony, however, the SDD-3000 also found a home in early new wave and 80’s synth music. Fully endorsed by KORG, the KORG SDD-3000 Digital Delay plug-in for UAD and Apollo interfaces exactly captures the original unit’s colorful analog circuitry, and burnished-sounding 13-bit delays.

Now You Can:

Tap into the song‑inspiring sounds of the legendary KORG SDD-3000 Digital Delay in a fully authenticated plug‑in

Add unique, chewy 13-bit delay, phase, flange, and chorus to guitar, synths, vocals and more

Get the dynamic interaction of the SDD-3000’s analog preamp stage with Unison™ technology for Apollo interfaces

Use Hold function to layer shimmering pads and soundscapes

An Iconic Rack Unit

Beginning with U2’s The Unforgettable Fire, The Edge took his guitar textures to a whole new level using the KORG SDD-3000’s responsive dynamics and colorful sonic palette. The Unforgettable Fire sessions turned Daniel Lanois onto the unit, and it has since become a staple of his studio and live rig, as well as that of electronic music icon William Orbit.

Legendary Delay

Legendary Delay

With just over a second of old school, 13-bit delay, the KORG SDD-3000 is famous for its percussive, rhythmic repeats. Like the original, you can select any value up to 1023 milliseconds, or you can simply use the plug-in-only Sync control to line up the repeats to your DAW’s tempo. The plug-in’s Delay Time window also features a handy drop down menu for assorted routing variations.

An End-to-End Circuit Emulation

An End-to-End Circuit Emulation

Universal Audio meticulously modeled a vintage "golden unit" KORG SDD-3000 Digital Delay, immaculately capturing its famed analog preamp and output section. Filled with JRC-made op-amps — the same type as many classic preamp, boost, and overdrive pedals of the era — the UAD KORG SDD-3000 Digital Delay plug-in precisely emulates this ultra-musical analog circuit.

Swirly Goodness

Swirly Goodness

The KORG SDD-3000 plug-in’s Modulation section is the secret to adding depth and motion to your echoes. Use the Intensity knob to adjust the pitch variation of your repeats, while the Frequency control conjures varying degrees of subtle movement and vibrato — crucial for long, Daniel Lanois-esque pillowy delays. Lastly, the Waveform selector lets you craft complex phase, flange, and chorus effects that are simply unobtainable with any other unit.

Feedback, Hold, and Filtering

Feedback, Hold, and Filtering

The Regeneration section of the KORG SDD-3000 plug-in is an ambient effect lover's dream. You can dial in simple slapback to long trails, or instant oscillation using the Feedback control. And, if you like what you've created, simply hit the Hold button and freeze that sound in place. Finally, the Filter controls offer tons of tone shaping, letting you add air or chewy warmth to repeats— perfect for guitars, synths, drums, vocals, and more.

Unison Technology for Apollo Interfaces

Unison Technology for Apollo Interfaces

Harnessing UA’s groundbreaking Unison technology, the KORG SDD-3000 plug-in delivers all the analog and digital goodness of the original with the impedance, gain staging, and quirky behaviors that have made the rack unit legend.

New Features

New Features

While the original KORG SDD-3000 had to be cabled up for a mono and dedicated dry out, the UAD KORG SDD-3000 plug-in gives you five options from a drop down menu. Plus, you can use a dedicated Position control to place the effect anywhere in the stereo field.

A Pleasant Surprise

Just love the range of rich sounds I can get from this for electric guitar. Adds a nice warm texture to boot. Wonderful stacked with akg spring reverb. Had to get it after I demoed it.

Great sounding delay !!!

I am the owner of a very famous early 80's hardware digital delay unit that costed a fortune in comparison and I must say that I was pleasantly surprised at how natural/warm the Korg SDD-3000 sounded especially using Unison Technology, it is a different flavor from my vintage rack mount delay to add to the tool box, very happy with my purchase !

Great sounding Delay not only for guitar...

easy to use special with Apollo Interfaces for performing in real time.
But why is the delay time limeted to a half note.....please spend a whole note for next update.....no matter if the original is not able to. 5 Stars anyway

Even better than the real thing!!

Incredibly warm delay with some unique twists.
Takes me back to my early guitar effects, delivering signature sounds on so many albums

If you want 80's vibe, this is it.

If I were new in UAD world and had to choose just two delays, my choice would be EP-34 tape echo and this one. Very musical, good color in delay but not too much. Just demo now. And you will buy it.

Hot, or is it cool?

I'm always a bit wary of reviewing things soon after getting them. But I can say that this plugin does some nice things. apart from the whacky effects you can get by modulating a long delay, something I've only previously got out of my old Yamaha E1005 analog delay, I've used a very short delay for flanging and it gives a very sharp flange that I haven't heard from any other plugin, with some interesting posibilities in pushing the delay up to around 10ms. Bit heavy on my poor old UAD-2 solo dsp, s'pose i'll have to go quad if I ever have the ££££ :-(

And another belter from UA

So easy to use uncluttered and uncomplicated and sounds even better than the original IMHO. GET IT!

Time for a delay!

I have waiting a lot for a real delay, and it's coming out, the best one. Now I'm waiting for the 2290.

I always wanted the hardware

Ever since I found out about this delay, I wanted it, but could never find the hardware until the pedal reissue, which I didn’t enjoy. Using this plugin with unison, I can get nice saturation and beautiful delay and commit right from the beginning.

Great Delay

I had one of these Delays in the 80's and really loved it then. I wished I had never sold it but when this came out on UA I knew I had to have it. Works just as well as the hardware with the usually additional features of a plug in such as the ability to match tempo in the DAW. I love the slightly lo-Fi sound that allows it to sit in mixes well. Home run again!!

Real Delay

I owned a tape and a digital hardware delay units in the past (late eighties). When I first demoed this plugin I immediately went back to 30 years ago because of the incredible richness of the effect that the Korg SDD-3000 can provide. I didn't think too much about it and i bought it. A must have!

Amazing response!

I own a lot of delay pedals and I was looking for a plug in that I could use for recording.
This one is from far the best I have ever tried, the response is amazing, you just get what you need. I use it with a pre eq to get the best of it, and the settings are very straightforward.
Definitely one of the best UAD plugin!

I immediately loved this delay. It works for so many applications.

This is a great addition to my system. It has the capability to smooth a vocal track, add feeling and provacation to a stringed instrument. It feels like hardware and finding your own presets is where the biggest rewards come. I love this delay more than any other.
