This is a USED 【DNVO-1a (Yellow Panel)】 from JMT synth, a company that produces many original drone & noise-based analog synthesizers. This model allows for more flexible operation with the addition of CV IN, etc. Although it's a noise-based synth, the VCO → Modulation x 5 allows you to create everything from harsh noise to rhythmic beats depending on how you operate it, and even clean sounds. By combining it with spatial effects, you can create deep drone music. There are minor scratches consistent with use, but overall, it's in very good condition. Please use your own DC9V adapter for power. Product Details URL https://beatsville.jp/products/dnvo-1a-beatsville-deluxe-edition?variant=34808865161370
