Yamaha reanalyzed and reevaluated literally every single design specification until they had created an instrument that harks back to the tonal purity and natural resonance of aged grenadilla wood. There’s less metal used on the YCL-CSGll, so the whole body reverberates with sound, while the new bore, barrel, and bell shapes offer a tone of breathtaking richness and depth. The sound is warm yet has a clear focused center surrounded by a wealth of overtones, resulting in extraordinary beauty and expressivity.
