The Boss VE-20 Vocal Performer is a voice effect device. It is a valuable companion for live performances but can also do great as a home recording device.
It offers the obvious but also extra effects for your voice. Compressor, Enhancer, Reverb and Echo, are of course in the list but also the Harmonizer, Looper with Overdubs and special effects like Electric, Robot- and Radio, Strobe (rotary), Distortion, Chorus, Flanger and Pitchshifting add to the collection off effects that you can combine as well.
I used the Harmonizer “Third and Fifth” for example in my 2018 song I Really Do.
The price of about € 200 is a little high though in my opinion but I am glad I have it at hand when I need it.
