Great, but with some limitations

By S Miller

from Wichita, KS

I use this for recording harmonized vocals, and vocoder, which is my favorite effect. It works best with octave harmonies that don't need to track to an instrument. It works OK with guitar but sometimes the original vocal cuts in. The guitar strumming also bleeds through a little, so you have to limit it. Harmonies are better with keyboard input, or I record MIDI, run it out to a keyboard and then back into voicebox. It really shines when used with different keyboard tones as input on vocoder. Adopts the tone of the KB. Good when mixed with different tones.

Not for live vocal performances

By Shawn

from Largo, FL

This item does not provide any real upgrade to enhance your vocals to that next level of live performance. In all circumstances there were occursnces massive amounts of feedback and distortion on the vocal channels. If you are looking to make those vocals have that extra punch buy a board with built In effects or a seperate rack mount vocal effects processor. I did end up rerturning it in for a refund. I am sure for an instrument inhancement application it would be great since I have used similar products for guitars.

Not quite up to par

By Gator Millhollon

from albuquerque, NM

The Voice Box is a nice little unit; however, it appears to not track the chords as well from a guitar as from a keyboard. It also appears to harmonize better with high pitched voices--females. I returned it after 3 days.
