How we ranked these vocal processors
Every pick has at least 100 customer ratings on Amazon and a listing with real specifications. The order mixes two things: how each model compares on the specs below (higher share of the best value in this group scores more), and how widely it is bought. The spec score runs from 9.0 to 9.8 and only compares these picks with each other. A spec the listing does not state is left out and the other specs are re-weighted; a listing with fewer than 2 stated specs is scored at half. We do not test gear in person. Full method.

Buying advice: vocal processor for live
Count the harmony modes first
Harmony modes set how many vocal harmony choices you get. The FLAMMA FV04 gives 11 harmony modes with 12 pitches, and the MOOER MVP2 gives 11 harmony modes with 12 pitches as well. The FLAMMA FV02 works on doubling instead, with chorus and reverb effects. If harmony is the point, compare the mode counts; if doubling is the point, the FV02 is the pick here.
Check phantom power and the power supply
Phantom power matters if your microphone needs it. The FLAMMA FV04, the FLAMMA FV02 and the MOOER MVP2 support 48V phantom power. The FLAMMA FV04 runs on an included 9V 500mA power supply, and the MOOER MVP2 comes with a power supply. Check the power supply in the box before you order.
Match the outputs to your setup
Outputs decide how vocal and guitar signals leave the pedal. The FLAMMA FV04, the FLAMMA FV02 and the MOOER MVP2 each give mixed or individual outputs for vocal and guitar signals. The TC Helicon PERFORM-V mounts on a mic stand and focuses on vocal effects alone, with 3 reverb, 3 echo and 3 double types. If you run voice and guitar through the same pedal, the mixed or individual outputs matter.
