Teenage Engineering OP-1

“Looking to sell my Teenage Engineering OP-1 digital synth. The synth is in perfect working order, including the speaker, sampler and radio.

There’s a few cosmetic blemishes from wear but they’re only noticeable up close. The only other things missing are the original box and the little gray feet, but the USB charge cable and rubber bands are included.

The OP-1 is an all in one portable music machine that is really fun to use once you master the interface. I’ve had a blast learning this instrument and hope it will go to a good home.” Click here to visit listing on eBay

“This OP-1 is around 8 months old and was purchased brand new by myself. I am the only owner. Unfortunately, I haven’t had the time to utilize it since I’ve been focused on video production as of late.

It comes with the original manufacturer foam box, usb cable, etc.

I am also throwing in one set of extra large custom knobs as well as a stand. Both products were purchased by myself for use with this OP-1.

The unit is mint, open box and hasn’t been used more than a couple of times. ” Click here to visit listing on eBay

“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 search for synths on eBay
