Casio Ct S1 Black 

The Casiotone user interface is elegant and simple, and perfected suited for a musical instrument, making them easy for anyone to use. A reduced number of buttons and knobs creates a sleek appearance, and the intuitive layout lets you find the desired control instantly.

The CT-S1 is designed to let you select the sound you want and get right into the music with a single button.

The Horizontal Bass-Reflex System is a space-saving technology designed to produce powerful bass, even from slim-bodied instruments.

Rather than being directly mounted to the upper housing, the speaker is mounted on a component attached to the lower housing, forming a dedicated enclosure (speaker box). Its solid structure enables the Bass-Reflex System to produce compelling bass while controlling distortion and sympathetic vibrations.
