Korg SDD-2000

Audio Proz Inv #: 27124

Sampling delay. 4 second delay. Interesting modulation effects and delay, vibratos, etc. Cabinet scratched up but in excellent low use condition inside. All cleaned and serviced.

"I like these machines but I persue them with some hesitation now because I find so many in such poor condition as to make servicing unviable. If I were to resell a properly serviced machine it would cost $300 now. To be honest though, there have been breakthroughs in technology whereby the new effects units by Behringer, Zoom, and Electro Harmonix all do these same tricks with better, more reliable performance (and they are cheaper!) I personally use the Behringer EM600 echo machine which can even emulate tape echoes but with a quieter noisefloor, better bandwidth, and in stereo too (for $50)! If you are hellbent on staying old school, keep in mind I do still work on Effectrons and ADAs which are still $100 – 200. I understand that people like using these device for sentimental reasons so I am glad to help keep them running, but I must say that for functionality and use; better money is spent on the modern equipment." - Vince

Orban/Parasound Model 111B

Audio Proz Inv #: 27295

Dual reverberation. Very good cosmetics, obvious ware, good faceplate. Fixed/floating limiting threshold, in/out attenuations, and bass/mid/sweepable EQ per channel. XLRs as well as barrier strips on back panel. Shortened/tightened springs for less muddy, brighter sound (tuned spring pans for ch matching). Altered input/output circuit to improve spring bandwidth and added spring dampers (foam) to reduce noise. Extra control added for high frequency enhancement, excellent for the "huge snare" sound. All switches and controls cleaned.

While great for its era, there are now similar units that do the sound imaging better than the 111b. The Behringer Edison or Ultra Fex, or DEQ2496 are all more sophisticated with better imaging correction, true stereo, etc and far more flexibility to reach into the depth of the mix. Low, mid, and highs can be separately adjusted.

Deltalab DL-4 Timeline

Audio Proz Inv #: 28254

SN#1533 512 millisecond delay @ full bandwidth. Flanging/doubling/chorusing echo. Digital octave flanging. Infinite repeat, resonant and doppler effects. Excellent condition unit, owners original unit, some noise modification. Does automatic step through delay. This unit features some very novel modulation of digital delay with a VCO which can operate as a square, sine, or triangle wave. As well, it does granular time based shifting of the delay line (ie. constantly shifting digital taps off the delay line). Very cool. This machine belonged to the owner and has never been roaded or misused.

FYI, Around the database you will often see us describe the condition of units on a scale of 1-10. #10 would mean the product is new from one of our suppliers, such as Behringer, Audio Technica, etc. #9 means the product is in perfect condition but is used, #8 implies there are some minor cosmetic scratches but unit is mechanically perfect, and so on and so forth.
