Korg SDD-1200 Dual Digital Delay from 1986

"Can delays have "a sound"? I'm not sure!

This is a rare beast: the Korg SDD-1200 was one of the last Digital Delay units in the Korg lineup from the 80's. It's a true "dual" architecture in that you can use each unit (A/B) as a totally independent delay. Or you can use them together, like I am here, to make some awesome sounding stereo effects from flange, chorus, vibrato, and typical delays.
There are multiple inputs/outputs on the back that let you wire it in unique ways. I have this setup in cross-modulation, where the A output is feeding the B feedback input for some great ping-pong like delays.
Here I made a little pattern on the MC-101, turning off built in effects so that all you hear is the effects from the SDD-1200

Pros:
•True independent signal paths for use as two mono delays
•12-bit processing and reduced fidelity, sits nicely in the frequency spectrum.
•Easy to get stereo effects with 2 LFO's that can be sync'd, or not.
•No presets = you have to dial in the sound!
•100% feedback sounds great, and better slowed down.
•Cheap (until this video!)

Cons:
•Changing delay times clears the buffer at each increment.
•Difficult to use dual-concentric knobs in tandem with each other.
•No presets for weak minded individuals!
•Somewhat rare."
