The PSR-EW425’s 820 voices deliver the same high quality that you’d expect from Yamaha’s higher-end models for a truly professional-level sound. The Super Articulation Lite button offers tones that capture the distinct qualities of specific instruments, like an electric guitar scratch or nylon-string guitar harmonics. Plus, Yamaha includes an incredibly realistic premium organ sound created with samples from Yamaha’s industry-standard YC range of stage keyboards.
