Polymoog

"Troubled from the start, this cantankerous instrument nevertheless found favour with a number of high-profile users, Rick Wakeman among them."

"[A] main element of any ABBA track is the synth lines, and it was the Polymoog that gave their music that distinct electronic vibe."

"[The Polymoog] was more of a performance tool, thanks to its ability to zone its keyboard with different voices."

"Offering organ-style divide-down polyphony and just eight presets, the Polymoog was an early attempt to create a polyphonic synth. It was certainly powerful, and capable of creating beautifully lush sounds, but became known for its difficult interface and poor reliability record."
