op1 “This is my Teenage Engineering OP-1 Synth/Sampler. This instrument is inspiring and a blast to play. The only reason I’m selling is to cover a massive tax bill.

The unit works perfectly. There’s a missing button cap which I believe can be replaced by Teenage Engineering. There’s also a slight scuff mark on the screen but does not effect operation at all. The USB cable is not the original but works exactly as it should for charging and data transfer. ” Link

op1 “Selling my Teenage Engineering OP-1 in mint condition; everything works as expected and no scratches etc. Kept in protective case in smoke free environment.

Letting it go since I am not spending any time producing music; hopefully you can give it the attention it craves.

Included is the original box and USB cable, protective case (non TE), Crank, Bender and Brick Shaft. Also including an USB stick with lots of presets downloaded from various places.” Link

Works great with no issues.

Thanks!” Link

op-1 ” Not sure if you’d be on this page if you didn’t know how special this thing is. Synthesizer, sampler, sequencer, 4-track tape recorder, mixer, effects module, FM radio, easy-bake oven, etc. etc., multi-award winning and permanently chilling in the San Francisco Museum of Modern Art.

Excellent condition. Minimal (nearly imperceptible) signs of bodily wear, perfectly clear screen, and all buttons and encoders are spotless and completely functional.

Includes the crank, bender, and FM transmitter, the official case by Unit Portables, official USB cable, and the two rubber bands from teenage engineering that came with the original package.

This machine was dearly loved and I hope it finds a new loving home.” Link

op1 “Super clean, barely used OP-1 that won’t turn on anymore.

I updated the firmware to the latest and the next day it no longer turned on. It makes a quiet “click” sound and nothing happens. It will boot into the system startup (COM + power), and all the tests run fine. The battery also charges fine. When it was working I had no problems!

I tried replacing the connector board, but it did not make a difference. I will include the extra connector board ($50 from iFixIt)!

Also included are the rubber bands and USB cable.

I don’t know what is wrong and I don’t use it enough to keep dealing with it. It is being sold AS IS!” Link

It has been minimally used over the last 4 months or so.

The coloured blur on the right of the boot screen is not a fault, this has been confirmed by TE as a “feature” of this firmware and in NO WAY affects performance.” Link
