KORG C1-BK - 88-Key Digital Piano with 30 Sounds and 50W Power Supply

The Korg C1-BK is a compact and elegant furniture-style digital piano that prioritizes the touch and sound of a grand piano at home, in academies or studios. It incorporates the RH3 (Real Weighted Hammer Action 3) keyboard with 88 weighted keys with real graduation (heavier in the bass and lighter in the treble), a selection of 30 high-quality sounds and a maximum polyphony of 120 voices . Its 2 × 25 W amplification system with 10 cm speakers offers more than enough volume and presence for a living room or classroom, and the two headphone outputs allow you to practice silently without disturbing anyone. The instrument includes a 2-track MIDI recorder (up to 14,000 notes), metronome, 50 demo songs and three pedals (damper, sostenuto and soft) with half pedal for greater expressiveness. In addition, it comes with an integrated stand with a slim design and is made in Japan .
