"This funky little analog synthesizer uses the very same SID chip found in the Commodore 64, and is credited (and blamed) for having popularized the so-called "chip tunes" sound. It was introduced in 1999 and discontinued in 2003 because Elektron ran out of SID chips. The SidStation is basically a monosynth, but you can sync all 3 oscillators for some crazy sounds. I'm the second owner. It's lived a happy life in two smoke-free home studios and remains in mint condition, with no known flaws. This is a very unique little machine, sold with the original power supply and owner's manual."
