The Roland E-4 is a clever little box for vocal experimentation. It’s perfect for singer-songwriters, beatmakers, and anyone wanting to add immediate, creative vocal processing without a massive setup. The vocoder is surprisingly good for the price, and the looper is a genuine boon for live performance.
