“Up for auction is a Teenage Engineering OP-1 keyboard with a non OEM power adapter. Everything works except the volume knob, which is
is stuck at half the volume. I got this this instrument like this and it really hasn’t been much of a problem for me, but you can buy the replacement board for about $50 on average (here on eBay or elsewhere on the internet, such as iFixit). Note: the volume knob can be physically moved, but it doesn’t alter the sound. All other knobs and buttons work fine.” Click here to visit listing on eBay

Teenage Engineering @ 04 September 2018, Comments Off on Teenage Engineering OP-1

“I’m selling my “like-new” OP-1 which features multiple synth engines (including a sampler), effects, various note sequencers and a built in 4-track recorder. I’m selling the unit because I rarely use it anymore. While I love the sounds and build quality, the OP-1 is better suited to more modern and experimental music.

This unit comes with its original hard case (including the original rubber bands intended to keep the case closed once opened), original translucent overlay showing what all the buttons do, original USB charging /connection cable as well as a new soft case that can hold the OP-1 keyboard and the USB charging/connection cable.” Click here to visit listing on eBay

“So you want one of these slick OP-1 synthesizers. But if you’re shopping for such a unique machine, you probably want the full experience that it can offer, as I did. The only problem is, the folks over at Teenage Engineering sell the accessories required to use certain features of the machine separately, and to be frank, the retail price of these accessories are too high to justify buying them new.

I bit the bullet and ordered most of these accessories anyway, as well as many other accessories that are useful for using the OP-1. Let my loss be your gain, and get them for cheap here, included with this listing.” Click here to visit listing on eBay

“Looking to part ways with this almost brand new unit. I messed around with this awesome synthesizer for 2-3 sessions before deciding to upgrade to a different synthesizer that better fit my workflow. All elements of the unit are fully functional, this thing really is fun to play (the possibilities are endless)! No cosmetic damage aside from the tiny blemish on the front panel (see photos) from my computer rubbing against it.” Click here to visit listing on eBay

“Teenage Engineering OP-1 Keyboard Synthesizer Sampler Travel Case with 3 Accs.

Add this incredible little machine to your home studio or take it backpacking through Aztec cloud forest jungles. It packs light and is built like a tank, and inspires one to dive in with with its ease of use and spunky retro gaming graphical interface. You’ll be wowed to no end with this and that’s a promise, or you can send it back for a full refund. This one here has been minimally used with no scratches, dents or dings to the OP-1, or to the nifty accessories. You will find the travel case has scratches on the metal button like feet on the bottom, and one of the sewn threads has been nicked (both can be seen in pictures), but besides that everything is in pristine like new condition – fresh and clean, without stains or odors.

The Bender, Crank plus 4 Extra Knobs, USB cord, and the 3.5 mm AM/FM antenna are included in this sale with their original boxes (some of the boxes are lightly damaged from shipment to myself about nine months ago), though I have the super rad packing papers (see picture above) which diagram basic start-up and some accessory function quite nicely.

All items have been tested and work 100%. They are flawless, cute, and functional adding an extra layer of playfulness to an already uniquely spirited instrument. As an extra bonus I have the original packing foam box (strange Swedish paper foam which looks handmade) container which I will ship it in, and I have all the packing materials including the helpful transparent overlay neatly describing all the button labels. ” Click here to visit listing on eBay

” I have for sale barely used OP-1 synthesizer. Looks like new because it only collect dust. I still have original box which includes one white cable and the grey cable. Grey cable – DOESN’T WORK – sometimes it’s charging, sometimes it doesn’t. SOMEONE WILL HAVE TO BUY NEW CABLE TO CAHRGE OP-1. Or you can use any other cable from your gadgets at home. I charged it few times with regular cable from my phone, worked perfectly fine. I’m adding radio antenna for free (cost me $20) in Guitar Center. ” Click here to visit listing on eBay

“Teenage Engineering OP-1 with rigid UDG carrying case & original packaging.

Got this maybe 2 years ago, and I used it very infrequently. I’ve really debated selling this, but I’m just not using it enough, so it’s time to let it go.

Kept in case when not using it, recharged the battery every few weeks. In very nice shape, everything that I’ve used on it has always worked flawlessly.”

“Barely used at all. Basically just taken out of original packaging. I am also including 2 extra knobs and a code to download Tonic from the Teenage Engineering website. Im not sure about the specification between analog and digital, but this works as a one stop shop. It’s a midi controller. A stand alone device that has its own built in speakers. You can even record a whole album on the OP-1 and then save it to your computer. It really is a crazy, miraculous, fantastic device. Unfortunately it just isn’t getting the dedication and attention that it deserves so I need to find it a new home. ” Click here to visit listing on eBay
