” As much as I’ve enjoyed having this OP-1 in my studio, it’s time for it to be put to use by someone else.

Function wise, it works perfectly. It’s been kept in a case, so it is completely dust free. That being said, the screen has some minor wear, the back of it has some scratches, and the cosmetics are in minor used condition. It’s definitely nothing that effects its usability. It works as well as it did out of the Teenage Engineering laboratory.

This offer is for the OP-1 itself and its charging cable.

Happy OP-1 hunting. ” Link

“One of the keyboard keys is a little loose (BARELY LOOSE IF YOU FLIP IT OVER) but not at all when you play or in a normal position. 0% of an issue. Literally stating this just because I like being very thorough. BARELY USED THIS. Maybe 4 -5 hours worth. Comes with box and cable!” Link

” This is a brand new Teenage Engineering OP-1 Keyboard Synthesizer that was taken out of the box and displayed behind glass for a short period of time. It was then put back in its original packaging to be sold here.” Link

“This item is fully functional, but is missing an USB Cable.” Link

“This is an OPEN BOX Teenage Engineering OP-1 Portable Synthesizer Workstation in Excellent Condition with a few darker marks on the back of the unit (see the picture circled with red that points out this small detail) ; film protection cover also has a few small black marks here and there but doesn’t affect the unit itself – there are no scratches on the unit at all.

This unit has been tested and it works great, sounds good, charging port works, microphone and line in works.

Teenage Engineering @ 22 August 2017, Comments Off on Teenage Engineering OP-1 Project Machine

“I have an OP-1 that won’t boot up. Used it for about a year, then it sat for a long time, and when I went to tried to start it up after a year or so of sleep, it seemed dead. Just to make it totally clear this unit DOES NOT currently power up and is being sold that way. I attempted a few different things to try to “wake” the battery, it sat for a week on the charger, but no luck. When you turn the ON switch, you can hear a faint click in the speakers that seems like there is life to the machine, but something somewhere isn’t working. It was a good machine when I used it, TE makes some amazing products of high craftsmanship. I never tried to take anything apart, so there’s no worry of any damage occurring that way.

I have other priorities and just don’t want to deal with sending it to TE to get it repaired, but you should be able to send it directly to them and they will get it working again! Even with cost of repairs you would still be getting a great OP-1 at lower than buying new.

Comes with TE USB cord and custom storage/carrying case.” Link

“This is a Teenage Engineering OP-1 Keyboard Synthesizer in like-new condition (I have only used it twice) with transparent overlay and USB cable. I bought it while hoping I would have much more time to use it than I did — I’ve had it now for several months and have only used it twice. It is a wonderful device, but I believe it can go to much better hands than my own. Whoever buys it will surely greatly enjoy it. It is updated to the latest firmware level. ” Link

“Great condition Teenage Engineering OP-1. Everything works the same as when I bought it: perfectly. Includes original quick-start overlay, USB cable, paperfoam box with bands, and protective hardshell case (Plano 1404), and it’s coming from a non-smoking environment. Small scratch under Shift key (see pic), two frozen pixels (could probably be fixed but it never bothered me), small crack on green knob (see pic, once again probably a cheap fix but does not compromise functionality so didn’t bother me), and paper foam box was stored under the second layer of foam in the Plano 1404 and is smooshed (see pic). I’ve had a blast with this and babied it as best I could. I’m moving so I have to sell this little gem…my loss, your gain. I really hope you have fun with this phenomenal instrument. ” Link
