Pedals
Discover a new realm of expressive possibilities with the AP-S450's carefully crafted pedals. These pedals are designed to capture the authentic feel and nuances of a grand piano. The damper pedal not only sustains the sound but also reproduces changes in resonance and adjusts its effect subtly depending on how deeply the pedal is pressed, allowing sensitive expression in your performance.
The soft pedal not only controls volume but also produces a more natural change in tone color, expanding expressive possibilities in softer passages. The slim AP-S450 features a continuously adjustable damper pedal. This design allows the decay characteristics to change depending on pedal depth, enabling fine and nuanced musical expression.
