The Korg SDD-3000 – perfect for LoFi?

By accident, I recently stumbled upon the UAD Korg SDD-3000 digital delay version. When I noticed that they modelled also its amplifiers as well as the 13bit converters they immediately got my attention. Having also high- and low-pass filters on board, this could easily double as a great lofi device – so lets have a closer look.

As in the original hardware, the device offers several gain stage adjustments for both input and ouptut, intended to match different instrument or line level signals. These amplifiers are always in, no matter if the BYPASS switch is activated or not. Interestingly, UA also integrated this in its “Unison” interface feature as an preamp option.

Depending on how hard the input gain is driven, quite heavy distortion and saturation effects can occur. As soon as the Bypass is deactivated, the effect signal path containing the 13bit converted and HP/LP filtered signal can be dialed in with the LEVEL BALANCE. If this balance is now set to EFFECT only or just the WET SOLO option has been turned on (plus avoiding any amounts of feedback in this case) the device now offers a pretty much nicely degraded signal path for any sort of creative effects. Depending on the actual settings one can dial in now some really creamy or even gritty effects. Be aware, that this signal path contains an additional delay according to the DELAY TIME setting, of course.

The analysis charts are showing – from left to right – the basic frequency response (in bypass mode), some example harmonic distortions when hitting the input gain quite hard and the filtered effect signal path frequency response according to the UI settings above. The slight frequency bump on the right side of the charts might be caused by the plugin oversampling filters – the original hardware does not show this and its spectrum ends somewhere around 17kHz.

As in the original hardware, all settings are just within limited ranges and so it is not that flexible in general. However, soundwise its pretty much awesome. Oh and by the way, it also doubles as a simple but impressive delay 😉

  1. Please take a look at the Meldaproduction stuff. It’s a big playground and can do so much, so you don’t need that much more.

  2. Would you mind capturing the waveshaper curve of the virtual SDE-3000 too?
    Thank you! 😊

  3. Great plugin from UAD, realy alive sounding delay !

    Thank you for this article. Just out of curiosity: Does that mean that your audio interface these days is from UA?

    • No, I’m currently sticking to my RME interface but if I will upgrade my DAW somewhere in the future to something Thunderbolt centric then I will consider them for sure. However, might be an issue of affordability …

        RME is a good choice: high quality, low latency, very reliable, excellent support – and total mix is well thought out. I have been using a Fireface 800 for years :-).
