Key Differences
Size & Tonal Quality: The GL-10, at 5'0", is ideal for smaller spaces but offers limited bass resonance. The GL-20 (5'2") provides enhanced bass response, while the GL-30 (5'5") delivers a richer, more dynamic tone due to its larger soundboard and longer strings.
Duplex Scaling: The GL-10 lacks duplex scaling, which affects the complexity of overtones and overall tonal properties. The GL-20 introduces dual duplex scaling for added tonal richness, and the GL-30 features full duplex scaling for a fully realized complexity and richness of tone with enhanced treble harmonics and overall resonance.
Manufacturing Origin: The GL-10 and GL-20 are manufactured in Indonesia, whereas the GL-30 is built in Japan, which may reflect differences in craftsmanship and quality control.
Structural Enhancements: The GL-30 includes additional features such as a fallboard lock and an extra lid prop, offering greater versatility which is especially useful in institutional settings.
Summary
GL-10: Best for those with limited space seeking a high-quality baby grand piano with essential features.
GL-20: Offers improved tonal depth over the GL-10, suitable for players desiring a more resonant sound and bass, without a significant increase in price or size.
GL-30: Ideal for serious pianists and educators looking for superior tonal complexity, bass resonance and dynamic range, with the added assurance of Japanese craftsmanship and a fallboard lock.
