"As a record producer, I have used this keyboard in countless productions over the years, including three singles for the mega group KORN.
Cosmetically, I would almost dare say she may be in near perfect condition. The only place that I can find a small scratch or two, is on the bottom underside of the keyboard. (See pictures). All nameplates are perfectly intact without a scratch. No scratches whatsoever anywhere on the top faceplate or keys.
This Pro One is also in excellent working order and sounds and plays amazing. I guess if you wanted to get extremely picky, you may be able to find a knob or two on the front that are a bit scratchy sounding when turning them. Feel free to message me, I could even text message you a video of me playing it. Showing that all keys work and it sounds amazing.
The only reason I am selling it, is because I have not been producing much dance electronica oriented music the past few years. I am primarily producing acoustic music."
Again, more interesting bits of individual synth history. Not sure how you would confirm this though.
"Unique creation by GlitchMachines.

"This is a great package, and a rare opportunity to own a legendary pair of vintage synth heavyweights in excellent condition. Both the MS-20 and the SQ-10 are in good working order and function correctly. The MS-20 comes with plastic Japanese overlay (see pictures) and a world-class R&R custom flight case. Original box and manual for SQ-10. Comes with 8 hosa patch cables. The MS-20 will ship in the green case; the SQ-10 will be double-boxed so the original box remains in its present condition."
"This is an Oberheim OBX-a as the ad clearly states. If you're here browsing chances are you already know the specifics of this beauty so, no need to list all the stats. Needless to say, it's big, it's heavy and it's lovely!! The story on this gem is, I was gigging with some cats who wanted to do a tribute to the 80's and me being the obsessive freak that I am, I had to have this board. Besides that, I've always loved Van Halen and Rush so, it was a no brainer. I bought this one on EBay from John Leimseider (look him up) who is the curator at the National Music Centre (look it up) in Calgary, Alberta. As fate would have it the tribute to the 80's never did happen for us and so, the board has been in my studio for the last number of years. Up until a short time ago when I decided to prepare it to be sold. I shipped it back to John who has gone over it thoroughly and has assured me it's ready to rock. When it's time to ship it will be well packaged and protected. Obviously, this item has been used. Consequently, there are signs of wear. However, the wooden sides are in perfect shape as are the keys. Everything works and it is completely functional. However, I would be remiss if I didn't mention that cosmetically it does have blemishes. There are a number of visible scratches on the top and what appears to be scrapes. I would say for it's age it's a 7/10 cosmetically speaking. Thankfully, this does not affect playability. This board is all original but John is able to install midi for a fee of course. Cheers!"
