Teenage Engineering OP-1

“This product is in fantastic condition. There are no signs of use (scratches, marks etc). It has been wiped and factory reset. It includes all the original cables, the original cover sticker, the original box etc, as well as a free carrying case (slightly too big for the device, but I use the extra space to include earphones, USB cable etc).

Apart from the fact the box is opened, this product is like new.

I am selling this OP-1 because I simply don’t have time to play it at the moment. I loved it and took great care of it.”

Teenage Engineering OP-1

“Brilliant little device. Multiple synth engines, tape recorder, sequencer, sampler, drum machine, radio, midi controls etc etc… I’ve had tons of fun with this. I’m only selling as I’m downsizing a lot gear and sadly this is one of the things that has to go.

I should say that one of the D sharp keys and one of the A sharp keys are a bit dodgy. Sometimes they play fine and sometimes they don’t. I think it’s just the connection that’s a little loose but I haven’t tried to fix it myself… by all accounts it’s pretty simple to fix. I’m just crap at the piano and mostly play in C so it hasn’t bothered me at all.

Everything else is in great working order. Mic/headphone port etc all working well (which are often common issues on second hand op-1s)

Comes with the case pictured and the original teenage engineering usb cable. ” Click here to visit listing on eBay

“Teenage Engineering OP-1 Keyboard Synthesizer Broken Does Not Turn On For Parts.

Condition is “For parts or not working”.

Shipped with USPS Priority Mail. Free shipping.

This OP-1 does not turn on. Even with prolonged charging, it does not turn on. There is nothing that shows on the screen or on any of the LED lights. I do not know why.

It worked perfectly fine for the 2 years that I have owned it (purchased used). Then one day, it simply would not turn on. It had never been abused or dropped. No water or liquid has ever been spilled on it.

Included are:
OP-1
original USB cable
clear plastic overlay
original black box
The protective soft case is also included

Not included:
the original rubber band that wraps around the box
I am not aware that this item came with a paper manual originally. No manual is included.

Everything seen in the photo is included.The cosmetic condition of the item is excellent. it shows just very light use with no damage or wear mark. These are the photos of the actual item that I am selling.

I have not attempted any repairs or any disassembly whatsoever. I believe this item will be more valuable to the buyer if I have made no attempt to take it apart or try to fix it.” Click here to visit listing on eBay
