Best Vocal Processor For Live Performance


A vocal processor is a device that can modify the voice with a multitude of effects to change its pitch, range, clarity, or special effects. Whether you are performing live or in a studio, you need to enhance the quality of your performance and also add as well as 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.

Thus, the use of voice processors is a little controversial. There are many modes to enhance the performances, and not all vocal processors provide all of them.

There are a lot of vocal processors available in the market today and I have handpicked and listed best 10 here in this article. Let's move on to the list now.




Let me start my list of the best vocal processor with the TC-Helicon VoiceTone Harmony G-XT. This vocal processor automatically generates vocal harmonies through an input signal.

It is designed to enhance musical performances by providing harmony generation, reverb, delay, automatic chromatic pitch correction, compression, and doubling effects.

The processor is based around 10 programmable presets. These programmable presets are available in 5 banks with variation A and B. You can easily build up the programmable presets using several features.

You can easily switch between the A and B variations with the left footswitch. The G-XT features loads of effect for you to choose from like, hall reverb, room reverb, echo, slap, and combination.

The device gives you a couple of harmony voices to choose from, Voice 1 and Voice 2. The Voice 1 offers higher, high, low, lower, bass, and octave up harmonies whereas Voice 2 has the same options, but replaces the octave up with octave down.

G-XT has a Tone button that with a single press adds a combination of EQ, de-essing, gating, and compression to smooth out the voice.

If you press it twice, it will start the automatic pitch correction which either works with the key of the chords you’re playing on guitar or from a manually selected scale. It also comes with VoiceSupport software that is designed for backing up user presets and installing updates to the pedal.

Customization of the presets is easy, these will come handy for you in live performances. The vocal processor offers great variations and features, but the variety of features can also be a problem if you haven’t acquainted yourself enough with this device.


  • Dimensions of 5 x 5 x 1.5 inches.
  • Weighing 2 pounds.
  • Natural play guitar-controlled harmony algorithm.
  • 6 reverb/delay combinations for vocal and guitar input.

  • Setting the key manually is difficult.



Next up in my list of the best vocal processor is taken up by the Roland VT-4 vocal transformer. The VT-4 features four front panel sliders for pitch, formant, balance, and effect mix. According to a user-specified key, the vocal processor has a central dial for Auto-pitch, which provides soft or hard quantization of your vocals.

The Formant control is helpful for adjusting the tonal construct of the vocal, using which you can make a male vocal sound like there are female BVs behind and, presumably, vice versa. The VT-4 uses new direct MIDI, which makes it very versatile.

The three modes of the VT-4 are robot, megaphone, and the main vocoder mode. The robot mode gives a monotone robotic tone with four variations and, the megaphone mode gives you megaphone-like quality to your voice.

The vocoder effect gives you a little more musical take on the previous robot patches, and the sound effects are bright and coherent. The vocal processor is a compact box that consists of a mono/stereo output on 0.25-inch jacks, MIDI input, microphone input on XLR and mini-jack, and USB input.

The VT-4 is designed to operate on vocals, although it has proved to be a handful while using other signals such as drums as a modulating signal. But if you require creating interesting and unusual vocal sounds, it is perfect for you. The device is powered by 4x AA batteries and has 5-hour battery life.
