It is 100% functional, has the latest firmware, plus a few bonus packs from Cuckoo. It comes with the radio tuner antenna so you can start sampling the radio right away!

1x – Radio Antenna (for radio sampling)
1x – USB Cable (for charging and upgrading)” Link

“Teenage Engineering OP-1 in perfect condition, only about 6 months old. Includes Crank & Bender accessories, accessory wallet, and display protector. The display protector has already been applied and the others are still in the packaging brand new. Also includes original usb cable, clear vinyl overlay with knob/button functions, and the silly Teenage Engineering foam box held together by official Teenage Engineering rubber bands. I will do an excellent job packing for shipment, bubble wrapping everything. Thanks!” Link

“This is truly like new condition, box was opened two months ago and it was charged up, ran maybe 30 minutes and stored away in its box. ”

“The OP-1 is fully functioning and works great, but is missing the blue knob and the speaker and headphone jack are broken,though they can be easily replaced. It only comes with a charging cable, no box, case, etc.” Link

“Up for auction is a used Teenage Engineering OP-1 with a bonus Kenton USB MIDI Host. The reason you’ll want the Kenton? It’s the easiest way to hook the OP-1 up to other hardware without using a computer. It can also charge the unit. I’m also including a soft case with some nice features (zipper, storage pocket, straps to keep the OP-1 in place). So this auction includes the OP-1, Kenton USB MIDI Host (with MIDI cable, power supply and USB cable) and soft case.” Link

“Just selling to make some money for other gear. I’ve had this for almost a year with no complaints, just not really my work flow. No functional issues, very minor cosmetic blemishes from regular use. Listing includes the OP-1, original box, and USB cable.” Link

“Latest OS installed. Built-in mic needs repair but recording input works just fine and otherwise it works just fine. The original styrofoam case has long since worn out but there’s no physical defects on the OP-1 itself. So no case but I’ll wrap it up well. Comes with original USB cable.” Link

Teenage Engineering @ 17 October 2017, Comments Off on Teenage Engineering OP-1

” 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

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
