On the initial recordings using the FV03, I heard two voices on playback, not unlike using certain plugins that are meant to higher the vocal register. After trial and error I managed to create something similar to what I was seeking: female backing vocals, but finally accomplished better results by turning the Mix to zero and just used reverb, then had to apply a bunch of filters in the DAW to achieve the sound I was looking for. The guitar input I found was of benefit only when I adding a pedal before it, but then the output signal and vocal audio are not separated, so I’m thinking there’s plenty of room for experimentation, but it was difficult to achieve what I wanted reasonably quickly, within a certain time frame.

Primero, llegó un día antes de lo previsto, bien empacado. Y ya hablando del producto es un excelente pedal Harmonizador de Voz, me encantaron las combinaciones que trae, se escuchan muy reales y nada robóticas, en una palabra Excelente.

If you're reading reviews you want to know if it will work for you, right? First, I will explain what it isn't. This pedal isn't studio quality at all. There is some noise in the vocal processing. There seems to be a build in compression that is always on. This makes the vocal sound a little squished. If you have a very dynamic voice it might get on your nerves. The reverb on the vocal cuts off when it reaches a certain level of decay I listened through a decent quality sound system and through a recording interface with headphones. Through the headphones it's hard to listen to. But for sound coming out of a speaker it's not really that bad. The reverb is usable. The doubling and pitch effects can add extra dimension if used conservatively. So, here's what it is. This is a good tool for a solo guitarist busker type to combine the mic and guitar into a single output while adding some effects to the sound. On a street corner, coffee shop or other noisy environment the shortcomings in sound quality will likely not be noticed. Even if you don't use the effects, the ability to combine a guitar and mic into a single output is useful for portable speakers that only have one, usually 1/4, input jack available.
