This OP-1 has never let me down and is fully operational other than external speaker

If you were to want to bring this unit to its original state it would cost around 69$ and 10 min to replace connector board. Anyone can do it with just a small screwdriver.” Click here to visit listing on eBay

“Hello! This is a Teenage Engineering OP-1 Keyboard Synthesizer. Its condition is “Used,” but as you can see in the pictures, the main volume control has seperated itself from the main board. **This does not disable volume control, as the orange control on the right also increases/decreases the volume or volume can be changed via an external audio source (headphones/speaker). Next, the frame of the OP-1 around the screen and area very close to it are barely curved outward **this is from the incident of the volume button popping out, and has no damaging effect to keys or the screen. ” Click here to visit listing on eBay

Teenage Engineering OP-1

” This is the famous OP-1 synthesizer, and it does not disappoint. It has incredible depth in terms of synth sound design, it is a great drum machine, has an outstanding sequencer, different arpeggiators, it’s a sampler (speaker and usb hookup), and it is a DAW (digital audio workstation) because of its recording and multi-tracking abilities. Overall, this thing is great. I’m selling it because I haven’t been using it very much (other obligations) and I think this thing should be making music.

Included: OP-1, original OP-1 USB cable, and the vinyl overlay that explains functions on the device.

I have included many photos of the device. It is in excellent working order with hardly a mark on it, there are two “notches” of note that I have pictured and circled. Otherwise this thing is pristine.” Click here to visit listing on eBay
