A redesigned resonating chamber helps produce the most realistic and "acoustic-like" string tones and resonating sound. The cello features an auxiliary input for playing along with an MP3 or CD player, a headphone jack for truly silent practice, and an output jack for performance. Three onboard reverb presets simulate the acoustics of a practice room, recital hall, and cathedral.
