DOD "Digitech" TSR-12

Audio Proz Inv #: 19997

Studio reverb/multi-effects processor, true stereo (well built), midi control, sampler, I/O attenuators, full bandwidth, 24 bit signal, 48 bit processing. Near perfect, low use condition. I was a Digitech dealer years ago. This unit is as new, used occasionally in my home synth studio. It has minor update to correct signal level into reverb DAC. It now can do +14dbm operation with 6db better noise floor. Most Digitech products of this era were IVL based designs, truly a remarkable reverb which bettered Lexicon for the money spent. It does some excellent multi effect, multi tape echo, flanging etc. with wide enough bandwidth, dynamics to be effective on my concert grand piano, etc. Most pros didn not give digitech enough credit. Very reliable machine.

Please note: only specific and slightly rare "CFC" memory cards can be used with the Repeater. The power supply is also rare, and at times only an expensive "industrial grade" power adapter ($100+) may still be available. Because of this, getting a whole package together can be expensive. The modification, CFC card, and power supply might total $300+.

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
