Teenage Engineering OP-1 Project Machine

“This is hard to part with. I love the op-1. I purchased new in 2017 when it was $900 (Sweetwater). I took good care of it, but suddenly the input/headphone jack failed on me in mid-2020. Only sound on right side with headphones in. Despite firmware update, factory resetting…I was told the DSP board had to be replaced. This took months ran me $400. (Triple S. Inc. NJ) I read this is fairly common. DSP BOARD REPLACED ONCE.

This week, I noticed the built-in speaker wasn’t working (which I never use) Sometimes it does, sometimes it doesn’t when I unplug the headphones. I hope this doesn’t lead to other issues. I’m assuming the worst and predicting it’s stemming from the DSP board again. Please take this into consideration when bidding. BUILT-IN SPEAKER NOT WORKING RELIABLY – DSP BOARD MAY NEED TO BE REPLACED IN THE FUTURE.

Otherwise, everything else is in great shape. Clean. One small scratch near the inputs (see pic) The Velcro tape was an attempt to mount it at some point. Nothing is wrong with the bottom. ” Click here to visit listing on eBay
