"Vintage Roland DC30 Analog Delay / Chorus Effects box. This is an magical mood & atmosphere generating machine. Anything you plug into it will sound amazing coming out. I'm a huge fan of the chorus and a bit of a delay freak, but this one has to go because of life circumstances.
It has enjoyed a peaceful and clean smoke free studio during my possession and leaves me looking exactly as it did when I originally picked it up a few years ago. There's a little rust on the metal housing, but it sort of builds character in my opinion : )
The unit functions perfectly and I should also mention a very cool feature is the ability to control the "Repeat Rate" of the Delay via CV on an input on the back of the Unit.
I've had amazing things happen while sending CV signals into the input on the back via my MFB Urzwerg Sequencer and shifting delay times while running a sequence.
Feel free to ask me any questions."

"Decided to sell this beast--CEM3340 oscillators + SSM2044 filters; considered by many to be the best sounding analog polysynth out there.
Just completely overhauled by Peter L. THE Voyetra tech. Everything was gone over in immense detail and updated where necessary. This is a green card rev. 4 and so responds fully to midi + sysex.
Cosmetically it is average, as seems to be the case with many of these (pics on request). Doesn't affect usage in any way. Also comes with a new old stock VPK-5 controller keyboard, recently purchased from the former head of Octave.
One thing to note is that the VCA/Filter trimmers are fairly sensitive--I had to re-calibrate upon receiving the unit--and this may occur again in shipping but I can advise on doing this.
Asking $7k shipped in the ConUS OBO
Loc: Cincinnati, OH
More than happy to meet in the OH/IN/IL region (to also avoid risking trimmer disturbance), and can adjust price accordingly if we meet."

Fun little piece on the Sequential Circuits Prophet VS, E-Mu Emax 1 and Kurzweil K2500s. You have to turn it up a bit. Be sure to turn the volume back down when done.
Update: Samples you can map:

"This particular one is fully serviced and in perfect working order.
Super clean inside and out, no leaky battery or any past battery acid damage inside on the circuit board(a common problem with these).
All the analogue sounds and voices work perfectly, even the programming section works properly...it's nearly always broken on these usually due to the ram needing replacement. No scratchy sliders, bad buttons or anything else.
This particular one also benefits from having a Roland Din-Sync connection on the back. Very useful!
Physically in superb condition, with only a few minor marks on the wooden case.
A truly amazing and iconic sounding drum machine that's been used on many hit records over the years!"
