Used Yamaha PSS-790 61-Key Keyboard 61-Key

Vintage Yamaha charm meets surprisingly deep synthesis in the Yamaha PSS-790, a compact keyboard that has earned cult status among collectors and sound designers. Originally released in the late ’80s, this model stands out for packing real FM synthesis capability into a small, portable format. With its distinctive retro styling and built-in speakers, it’s a throwback piece that still delivers unique, character-rich tones.

The PSS-790 features Yamaha’s two-operator FM engine, allowing users to edit and create their own sounds rather than relying solely on presets. That means glassy bells, punchy basses, quirky leads, and classic FM textures are all within reach, especially for players who enjoy diving into sound design. It also includes built-in rhythms and accompaniment features that reflect the era, making it both a creative tool and a nostalgic time capsule. A power supply is included so you can plug in and start exploring those unmistakable FM tones right away.
