Critic Reviews

Electro-Harmonix Voice Box review | MusicRadar

musicradar.com

The Electro-Harmonix Voice Box impresses as a vocoder with its 256-band clarity and offers a range of natural harmonies, though it demands precise input for consistent results. The device boasts a robust design and a variety of inputs and outputs, making it versatile for different setups. While the vocoder is lauded for its clear diction and flexibility, the harmony generator can be temperamental, requiring in-tune vocals and steady levels. Despite these challenges, the Voice Box's vocoder quality alone justifies its price, making it a strong choice for those focused on vocoder capabilities.
