The traditional style AC models have been re-engineered to improve resonance for an authentic classical guitar sound. The nice combination of tone-woods yields a traditional, deep and delightfully mellow tone. Cort AC series is very forgiving of student mistakes, requiring slightly less precision and sharpness for a good tone. The AC100 features a Spruce top, Mahogany back and sides, Merbau fingerboard and Savarez crystal strings.
