Casio Casiotone CT-370 49-Key Keyboard - Used
The Casio CT-370 is a late 1980s Casiotone built around PCM sampling — a big deal at the time — with 49 keys, 20 preset tones, 20 rhythms, auto-accompaniment, auto-harmonize, and a tone mix feature that lets you layer any two sounds for up to 210 combinations. No velocity sensitivity, no MIDI, one built-in mono speaker — but that's not the point. This is a charming, lightweight, portable vintage keyboard that excels at organ and synth tones and is genuinely fun to sit down with. A good basic inexpensive keyboard to enjoy.
This one is fully functional with all keys and controls working. Cosmetically it shows scratches and dings consistent with regular use, and there is some more significant housing damage worth noting: a few larger cracks and chunks of plastic missing from the housing on the treble end, and cracked corners on the bass side. Nothing that affects playability, but buyers should check the photos closely. No power supply included — takes 6 D batteries or a DC adapter.
Condition is Very Good.
