Korg SDD-3000 Digital Delay £149
If ever proof were required that not all delay effects are born equal, the SDD-3000 is exhibit A. Released in 1982, Korg’s rack-mounted echo unit fell into the hands of U2’s Edge and the rest is rock/pop history. However, there’s plenty here if you’re more of a synth-smith than an axewielder. Each module is clearly labelled, with temposync’d or millisecond-based delays flanked firstly by a frequency-selectable Feedback knob, which can provide everything from single subtle echoes to multi-tapped layers. The Modulation section introduces transformative effects in a variety of ways (including LFOs, Envelope and Random triggers) to produce delay, flanging, phasing and chorus treatments. A flexible, warm-sounding echo unit which beautifully echoes the 13-bit colour of the original.
