“Barely used OP-1. Great condition. Screen is in perfect condition with no scratches. There is a small discoloration on one of the black keys which can be seen in the photos. This is not a scratch and cannot be felt on the key itself. I think it gives this particular OP-1 some character and makes it easy to identify. Otherwise the condition is perfect. It has always been stored in the case as long as I have owned it.

I really love this device, but haven’t had enough time to put into it, and I hope it finds a really nice home.

Comes with the the official case, original Teenage Engineering USB cable and one patch cable.” Click here to visit listing on eBay

” Here we have an OP-1 that is essentially brand new. I bought this when I was traveling a lot for work and thought it would be an excellent tool for songwriting while on the road. Well, it took me no time to figure out that I’m a guitar player through-and-through. I never even used the OP-1 enough to understand its functions. The original case and plastic layover have gone missing. However, the original USB cable comes with as well as a handgun case that functions perfectly for the OP-1. If you have any questions, I’m more than happy to answer them. I guarantee the OP-1 to arrive fully functional, no different than a new purchase. Insured, quality pack job and shipping included in purchase price.” Click here to visit listing on eBay

” Very lightly used OP-1 only about 5 hours of use, only been recharged once.
Just couldn’t get used to the workflow on this synthesizer.

This was purchased new from the MoMA design store in late July 2018. Receipt is in the pictures.

Teenage Engineering @ 16 October 2018, Comments Off on Teenage Engineering OP-1 Project Machine

“This OP-1 is in good overall condition and mostly functional, but has some issues:

1) The volume knob does not change the volume. Current volume is set at a useable level but cannot be changed. Volume pot feels wobbly but does turn correctly.

2) Three of the keyboard keys plus the “6” key are not responsive. See photo 11 for a shot of the unit with these four keys removed.

3) Power switch feels sluggish but does work fine every time.

All other controls have great feel and respond accurately. All lights and screen fully functional. All ports and jacks in great shape and connect without issue. Sound is strong and clear from all inputs and outputs. Battery is charging well and holding a charge. No issues mounting the unit as a removable disc on a computer via the USB cable.

The unit passed all practical tests and self-tests with the exceptions of the faults listed above. It has been updated to the most recent 225 operating system.

Sale includes the unit with its original USB cable.

This is being sold as-is, for parts or not working, with no returns. ”

“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

“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
