Best Vocal Effects Processor Reviews + Buyer’s Guide


A vocal processor is a device that can modify the voice with a multitude of effects to change its pitch, range, clarity, or special live vocal effects.

Whether you are performing live or in a studio, you need to enhance the quality of your performance and also manipulate the existing effects.

These devices are generally small, compact, and light in weight and boast several features like echo, reverb, loop, voice gender manipulation, and much more. 


Some people feel the use of vocal processors can be the easy way out for singers and performers, as the performance or the voice isn’t natural and is somewhat artificial, as it is enhanced with effects with the help of technology.
