CASIO CT-S1BK Synthesizer (Black)

CASIO CT-S1 BK Casiotone Keyboard

Casio CT-S1 BK – a modern classic in a compact format. This Casiotone model stands out with its elegant, all-black finish and minimalist design that never goes out of style. The black casing with matching textile speaker grille creates a seamless, solid look, perfect for both a home studio and the stage.

Despite its compact size, the instrument surprises with its sound quality. Inside, an advanced AiX sound source reproduces 61 carefully selected tones with impressive detail. The collection includes not only realistic pianos, but also "CASIO CLASSIC TONES" – 12 legendary sounds from Casio's history of the 80s. A special horizontal Bass Reflex speaker system ensures deep, clear bass frequencies and a spacious sound that you wouldn't expect from such a thin instrument.
