Let’s be real – nobody wants to sound like they’re singing through a tin can wrapped in a wet blanket. That’s where these vocal processors come in, turning even your shower singing into something your neighbors might actually enjoy.
Before diving head-first into the technicolor world of vocal processors, we did something revolutionary – we actually asked singers what they think! We surveyed dozens of vocalists on the MG platform, from shower-singing enthusiasts to touring professionals, to find out which vocal processors actually deliver in the real world. Their battle-tested insights helped us separate the genuinely voice-transforming from the glorified paperweights.
Whether you’re looking to add some arena-sized reverb to your bedroom recordings, create harmonies without needing to clone yourself, or transform your voice into a robot from the future – these magical boxes of vocal wizardry have got you covered.
We’ve tested units across all price points, feature sets, and use cases to bring you the definitive guide to the best vocal processors available in 2025.
What to Look for in a Vocal Processor
Before dropping your hard-earned cash on a shiny new vocal processor, here’s what our vocalists recommend considering:
Effects Library: From essential reverbs and delays to wild pitch-shifting and vocoder effects, the breadth and quality of available effects can make or break your purchase decision.
Interface Usability: As one touring vocalist told us, “If I can’t figure it out in 10 minutes before a gig, it’s useless.” Look for intuitive layouts and quick access to essential functions.
I/O Options: XLR inputs for microphones? Instrument inputs? USB connectivity for recording? Make sure it plays nicely with your existing setup.
Form Factor: Are you a pedalboard warrior or a desktop dweller? Size matters when you’re trying to cram yet another piece of gear into your setup.
Price-to-Feature Ratio: Sometimes the most expensive option isn’t the best for your specific needs. Consider what features you’ll actually use rather than paying for the kitchen sink.
Now, let’s dive into our top picks, shall we?
