10 Best Vocal Harmony Processors 2026 in the United States

The Boss VE-22 Vocal Effects and Looper Pedal is designed for vocalists looking to enhance their performances with harmony and effects. One of its major strengths is the ability to generate multiple harmony voices, which can be particularly beneficial for live performances. With 99 user preset slots and 50 factory presets, it offers a wide range of options for users to experiment with various sounds and effects, making it suitable for both beginners and more experienced singers. The USB-C audio interface is also a great feature for those who want to connect the device to a computer, allowing for easy recording and playback.

While the VE-22 shines in many areas, it does have a few drawbacks. The user interface, though functional, can be a bit complex for those who aren't tech-savvy, potentially requiring some time to learn how to navigate the functions effectively. Additionally, the pitch correction feature, while useful, may not be as comprehensive as some dedicated pitch correction tools, which might disappoint users looking for professional-grade pitch adjustment.

In terms of connectivity, the pedal provides a solid range of options, but it could benefit from more modern connectivity features such as Bluetooth. The compact design is a plus for portability, making it ideal for gigging musicians.
