Voice Box Vocal Harmony Machine/Vocoder
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.
Diana Ross had the Supremes, Brian Wilson had the Beach Boys, Kraftwerk had The Robots. You have the Voice Box.
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.
Plug in your mic and your instrument, and let your new voice—or voices—be heard!

Timely Tone TIp for Changing Presets.
People have complained of having to bend down during a performance to change presets on units like the Stereo Memory Man/Hazarai, The Ring Thing, Voice Box and the Cathedral.
What many do not know is that these pedals were ergonomically designed to be controlled by your feet.
The white preset/mode knob is perfectly positioned to be operated by the side of your right foot.
Use the side of your foot to select the preset position. Then carefully tap straight down on the white knob to activate the preset.
With a little practice your feet will be in control. Then you’ll be able to keep your hands where they belong…on the guitar!
Below is a demo video:

Here’s the latest videosong by the multi-talented JRENG! This time he’s collaborating with Lola Bangs The Drums, a duet featuring Natalia Pratiwi and Dika Charles Dickson.
The title of the original song is “Dekati Aku” which translates to “come and get me!”
When producing this videosong JRENG! drew inspiration from big band, swing music. He explained that because he doesn’t have brass instruments he mimicked the brass with his pianica and an EHX Voice Box in unison mode (one octave higher, one octave lower).
JRENG! used the following EHX products in this production:
Voice Box (pianica)
Cathedral Stereo Reverb (electric guitar, electric piano, acoustic guitar)
Stereo Pulsar (electric guitar)
Russian Big Muff Pi (bass, lead synthesizer)
Double Muff (electric guitar)

Tommy (that’s her name) manages a ukulele shop in Japan. Here she performs the classic B.J. Thomas tune, “Raindrops Keep Falling on My Head” using an EHX Voice Box Vocal Harmony Machine/Vocoder.
The Voice Box can create 2 to 4-part harmonies directly from your vocals in the same key as your accompanying instrument. Its studio-quality reverb adds depth and ambience. The whistling in the last verse is from the Voice Box!

Well before the advent of products like the new V256 Vocoder, Voice Box and Iron Lung, Electro-Harmonix was breaking fresh ground to bring innovative and affordable vocal processors to musicians.
This ad, for the original Electro-Harmonix VOCODER, is over 30 years old and dates all the way back to December of 1978!
