How to Choose The Best Vocal Effects Processor - 3 Key Features to Look For

a vocal processor connected to the computer

As you can see from even the small sampling of models we’ve covered here, vocal processors come in many shapes and sizes with unique features. With so many options from various brands, finding the perfect one for you may prove daunting. To help with this, here are the most important features to look out for when trying to select the best vocal processors for your needs:


Looking through processor reviews, you’ll see that the best products all have something in common – the ability to add several harmonies while singing.

This feature is a vital one in a live vocal processor, regardless if it’s for studio or stage use. With the ability to add harmonies, you’ll be able to add and combine guitar inputs or inputs from other instruments to adjust the harmony and pitch of your singing to fit the instrument’s chords.

Even better are vocal processors that offer Smart Harmony, which automatically adds backing vocals to enrich your singing. It’s especially useful for singers who have weak vocals.

The number of harmonies that you can add (and how much you can tweak them) will vary from processor to processor. For the best results, go for a vocal processor pedal with a harmony feature that matches your needs.

Pitch Correct (Auto-Tune)

While certain artists have abused the use of auto-tune, it’s nonetheless a useful tool for fixing tuning issues. Top-notch vocal processors give you the power to control the level of auto-tune in a song. The more control you have, the better the results you can get rather than excessive or ineffective auto-tuning.

Vocal Effects and Looping

If you want consistent control over EQ, compression, delay/reverb, or other basic vocal effects, you need the right voice processor. The typical processor only offers core effects. More versatile models offer more options like alien, vocoder, robot, synth, and more for unique audio results.

The processor may also offer options that let you deepen or soften your voice through formant shifting. Do it correctly, and you can make a female artist sound like Barry White or vice versa. You can also use such effects to keep a singer in tune or use it to replace backup singers and add harmony to your song.

Another useful effect is the guitar effect. For artists that sing and play guitar, a processor that offers this effect is the perfect “all-in-one” performance unit because it means you won’t need a separate voice and guitar pedal. This keeps equipment overhead down and a performer’s rig less complicated.

What are the Differences Between a Regular and Pedal Vocal Processor?

The majority of effects processors are useful for adding effects like voice doubling, echo, reverb, and more to boost the quality of your song recordings or live singing. All these effects and more are accessible to turn you from a regular Joe to someone who sounds like the ultimate rock star or an R&B angel.

The design of most vocal processors makes these effects accessible with just the push of a button or the turn of a dial—but that is only convenient if you are recording in a studio. If you are performing live on stage, having to pause to change effect settings may distract from your performance.

Fortunately, there's a perfect solution, and it comes in the form of pedal vocal processors.

Pedal vocal processors, also called stompboxes, are a popular choice among singers who are performing live with guitars. Such performers prefer pedals because it allows them to multitask.

For example, while singing and playing the guitar, the performer can conveniently use the pedal to select vocal effects on the processor and harmonize with the guitar. The alternative to this (if using a non-pedal processor) would be to stop playing the guitar to change the effects by hand.

Stompboxes typically have multiple switches, so you'll need to be quite nimble to hit the right buttons with your feet when necessary. Regular vocal processors, such as tabletop and stand mountable types, on the other hand, are better for DJs, studio recordings, or live performances where the singer’s hands are free of instruments.

As the name implies, a tabletop processor can be on a table or DJ station, while mountable vocal processors are attached to microphone stands.

Which Vocal Processor Should You Choose for Live Performances?

Based on our experience and what customers have to say, we pick the Boss VE-5 as the best voice processor for live performances.

The Boss VE-5 is perfect for live shows because you can attach it to your microphone stand and control it directly without interrupting your performance. It also comes with a wide variety of effects that you can use to boost the quality of your vocals. On the downside, if you are a singer and guitarist, using a VE-5 may interfere with using your guitar. If you’re going to be playing the guitar, you may be better off with a stompbox like the Boss VE-20.
