” Teenage Engineering OP-1 Keyboard Synthesizer. Used. I am the original owner and unit has only been used by me.Works great. Good battery life. Comes with carrying case, keyboard layout plastic, USB cable, and 2 spare knobs. Selling because I just don’t use it in my workflow at all.

Has a slight defect as pictured that does not effect operation or performance of the synth. The defect is next to the braille on the back side of the unit. The plastic is slightly cracked. I am convinced this happened because of the stand I had the unit on, but the unit was never subject to impact. Again, the unit works fine.” Click here to visit listing on eBay

“Selling my Teenage Engineering OP-1, as popularized by YouTube channels like Red Means Recording and Andrew Huang. The unit is in outstanding condition, only ever used at my desk, no gigging or travel. I just don’t use it enough, but it’s an amazing little synth. Purchased new from Teenage Engineering in September of 2017.

Note: The foam box that the OP-1 came with warped while being stored in my attic, but the OP-1 still fits inside. I did NOT store the OP-1 in my attic, it’s been on my desk the entire time I’ve owned it. ” Click here to visit listing on eBay

Used for 15 minutes, it has been in its carrying case since. Comes with its Unit Portables case, USB cord, rubber bands as well as the additional add-ons Crank , Bender and Antennae.

“Teenage Engineering OP-1 Keyboard Synthesizer with case and extras.

Purchased 11/13/17 from Musicians Friend and used for under two hours.
Comes from a non smoking home and has never seen outside the home use. I literally bought it, made the case and put it away in storage. I take it out once a month and give it a charge just to keep the battery happy. The battery indicator lights have never worked right… they do the usual OP-1 weirdness. They show its charging, but it never shows full. Pretty common if you look to the forums.

I built this case from an old “pov RC flight case”. It used to house a small monitor and some other flight equipment. Now it is home to the OP-1, which is plugged into a Belkin five way splitter, which is plugged into an Alfway bluetooth speaker. With this setup you can run the op-1 and four other instrument into the Alfway speaker. Its a pretty sweet setup for on-the-go blooping and bleeping. Ive included a list of everything you receive in this sale below, with a short description. Feel free to ask any questions!

Included with sale:
* (1) Teenage Engineering OP-1 with original case, overlays and rubber bands and charging cable. (firmware R.00225)
* (1) Teenage Engineering Antenna for OP-1
* (1 SET) DJ TechTools Chroma Caps (nice, easy to grab knobs… much better feel!)
* (1) yellow 3D printed crank
* (1) DIY Case (its not perfect, but its a great place for the op and accessories)
* (1) ALFWAY Bluetooth speaker with instructions. 10 watts. 3,000mAh rechargeable battery. Speakerphone. FM mode. Bluetooth wireless. Really cool little speaker that was bought for another project but fit this case really well. It can also be used as a power bank to charge other devices or phones.
* (1) Belkin 5 way splitter hub thing.
* (1 SET) 3D printed stands with rubber, non-slip feet. I printed them with a pretty high fill rate, so they’re pretty weighty. Good stand for table top operation though.
* (1) Printed manual in white binder
*** The only thing not included in the photo is the white charging brick. Thats mine and you can’t have it.” Click here to visit listing on eBay

“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
