Teenage Engineering OP-1 Synthesizer Unboxing Video Here’s an unboxing video (a deviant niche of synth porn, if there ever was) for the Teenage Engineering OP-1 synthesizer. Yeah, it’s expensive. But it’s still a pretty sexy box. The video is via sonicstate. Nick’s going to do a review on the OP-1 synth, so let him know if you’ve got questions.
