I bought this pedal to put my saxophone through, and add reverb to my sound. It did this very well. I did use some of the other features (of which there are many), but in the end, I just use reveb on our PA now, so I am selling my pedal.
I think it is pretty much industry standard these days. 

The VE-20 gives you a compact and affordable way to add extra effects and harmonies to your vocal performance. Although packed with features, the VE-20 is small enough to go into a side pocket of a guitar gig bag and can run on six AA batteries, or an external power supply. Essentially for single vocal live use, there is a balanced combo-jack/XLR connector (with phantom power +48v) for mic input, stereo balanced XLR outputs (which can be set up as stereo, or one mono FX/one dry) and an additional line/phones out on stereo 1/4” jack.
the Boss VE-20 is a great FX pedal for a solo performer looking to add a little something to their set-up, but is equally at home being used as a global reverb/delay effects unit in a band situation. It's definitely one to audition.

I'm just a musician that plays and records at home. I'm not a good vocalist. This is a very cool pedal. It helps make me sound better and has a bunch of great features. I absolutely love it. It can be used for live performances or plug it right into your recording equipment. Personally i can't imagine not using now that I have it. It's now a staple when recording. My voice still sounds like my voice but it helps with the pitch. It's not like some cheesy auto tune. I love all the options. You can look them up for yourself on the product description. If your like me, you don't have a great singing voice, but want to do vocals, this is a great addition. We'll worth it.
