The Electro-Harmonix Voice Box vocal harmony processor/vocoder makes it easy to get a variety of cool vocal effects and multiple harmonies, effortlessly! The Voice Box lets you generate 2- and 4-part vocal harmonies by keying off of your guitar or keyboard. You can blend effects, add the onboard reverb, and even dial in "male" or "female" formants to your liking. You get nine presets with a dedicated footswitch, plus a mic bypass switch, too. Why let the instruments have all the fun? Get creative with your vocals and plug in the Voice Box!

Electro-Harmonix Voice Box Vocal Harmony Processor/Vocoder at a Glance:
  • Backup singers in a box
  • Use your instrument to drive your harmonies
  • Generate amazing vocoder sounds

Backup singers in a box
The Voice Box packs a multi-functional vocal synth processor into a tough and compact chassis. Sing, and you'll have a troupe of backup singers following you in perfect harmony. Or use the built-in vocoder to unleash classic synth-robot sounds.

Use your instrument to drive your harmonies
The harmony processor creates 2- to 4-part harmonies directly from your vocals, in the same key as your accompanying instrument. Studio-quality reverb lets you independently add depth to your dry and harmony vocals.

The focused 256-band articulate vocoder, designed by the same EMS genius who made vocoding famous, features adjustable harmonic enhancement and controllable formant shift. It's incredibly easy to turn vocals into an inspiring instrument with the Voice Box. Intuitive controls give you instant results to fire your creativity.

Wonderful addition

I bought the Voice BOX July of 2017. Well, now that were COVID-19 homebound I thought I'd finally write a review.
My wife and I perform together. I play the guitar, she plays the Ukulele and we both sing.
We use the Voice Box at every gig.
We both can sing harmony for the other, but some songs need more voices. We narrowed our harmony settings to 4.
It's a wonderful addition.
In 2019 we had 87 gigs. In 2020 we played 14 gigs before everything shut down. We can't wait to hit the road again. Be safe

Great vocal processor

This is the second similar vocal processor I have bought, thus one is the better of the two... it tracks really well, and follows my guitar key accurately. You can make multi part harmonies sound good, or you can just dial a little reverb in if you are looking for a more subtle effect. The band and I definitely like messing around with it, can't wait to use it live when that can happen again. One note is that it is probably best not to run on your pedalboard unless you are sticking with just one setting. I mounted it on my mic stand, and can adjust much easier on the fly.

Perfect for the home studio...and always great service from Sweetwater!

I bought the Electro-Harmonix Voice Box for use as a home studio gadget, and so far so good....and Sweetwater's processing, shipping speed and follow up are second to none!

The Voice Box is awesome

I just bought the Electro Harmonix Voice Box and it rocks. The vocoder works great and sounds really cool when it's triggered by a guitar. The harmony modes work great, just as long as you sing on pitch. If not, there's still the octave and whistle mode that work great and don't have to follow the key you're playing in.

The Voice Box also sounds really cool when you put horns through it instead of vocals. It's definitely a sick toy.

What Do Our In-house Gear Experts Think?

Jared Kalish

I've been using this box for use in my live solo performances to give me a bigger sound onstage during key vocal parts, but I actually find myself using it in my studio just as much! The built-in reverb and multiple harmony patterns really allow me to be creative when writing or tracking and the intuitive controls and nine presets let me focus on the music instead of fiddling with the box itself. What a great creative and live tool!
