The Realistic Concertmate 350 is a classic, mid-sized portable keyboard from the late 1980s, originally sold through Radio Shack. Designed for simplicity and fun, it features 37 mid-sized keys and is a rebranded version of a popular Casio model from the same era. This keyboard is a favorite among lo-fi enthusiasts and circuit benders for its charming, early digital square-wave tones and iconic "retro" aesthetic.
The Concertmate 350 offers 4 specific preset sounds—Piano, Fantasy, Violin, and Flute—along with 10 built-in rhythm patterns to play along with. It also features a "One Key Play" function and a simple melody memory sequencer, allowing you to record and play back short musical ideas. While it doesn't feature MIDI or velocity sensitivity, its lo-fi character makes it a unique addition to any modern studio looking for vintage 8-bit textures.
This unit is in very good condition and has been fully tested in our shop. Every key triggers reliably, and the built-in speaker is clear and free of distortion. The battery compartment is clean with no signs of previous corrosion, and all slider controls move smoothly. It shows only light cosmetic wear consistent with its age, such as minor surface scuffs on the plastic chassis.
