FLAMMA FV02 Doubling and FV03 Character Vocal Pedals
The Flamma FV02 Doubling and FV03 Character pedals are very useful pedals that can inspire creativity and fun! Each provides its own unique spin on vocal alteration. With the FV02 Doubling, you can double your voice or have an ensemble of you. Or, you can add a pitch shifted version of yourself, either as a baby voice or an octave down voice, or both! The FV02 gives a chorusing effect. With the FV03 Character, the first setting pitches your voice a tritone down, perfect for a horror vocal voiceover. Or, you can pitch your voice up an octave to female or baby timbres. Or, you can have a vocoded robot drone in three varieties and sing a melody over it. The Blend knob will allow you to blend your natural voice in as much as you like. Both pedals can add reverb to your vocals, available in three types, which all sound very nice. Both pedals have a nice option of disabling only the vocal mode effect (indicator around switch turns red) while keeping the reverb, or double click to turn both effects off (unlit). The guitar input is designed to give your guitar a little bit of reverb shimmer and works best with an acoustic-electric or clean electric sound, but you could certainly run your guitar into a distortion pedal then into the Doubling if you wanted some distortion. I wouldn’t distort your sound after the doubler because you’ll want to keep the reverb clean and crisp. One tip: Don’t let your input signal be too hot. I had the best results using an external mic preamp with output volume set fairly low. With this setup, you would switch the XLR input to line. The other useful option is just to plug your mic directly into the pedal. I used a good dynamic mic and set the gain about halfway on the Doubling and 2/3 on the Character. Use a small flathead screwdriver to turn the gain knob. Be careful not to set the input gain too high or you will get a very loud, nasty squeal back! The enclosures seem sturdy, and I love the vibrant colors! All in all, these are nice pedals that can add some creative effects once you learn how to use them.

Vocal Helper
This pedal adds a variety of helpful features for vocals, including EQ modes, three kinds of reverb, three kinds of delay, and of course, pitch correction. The pitch correction is subtle. You aren't going to get Auto-tuned vocals out of it, but it will help if you slightly flub a note. There are a variety of routing options to allow you to have an instrument pass through to detect the key of your music for the pitch correction. There are also options to route both instrument and vocals either through the 1/4" or XLR output. I found that with the signals merged, the instrument was far louder than the microphone, even with the microphone gain turned all the way up, so if you plan to to use a single output, you may need to attenuate your instrument signal or further boost the microphone signal prior to this pedal. Using separate inputs posted no problem, and the phantom power worked well. This could be useful simply as an easy source of phantom power for those cases where it is not otherwise available. The reverbs and delays sound very nice, but only the reverb can be used on the instrument signal, while both can be used on the vocal. Overall, this is a very useful toolkit for vocals featuring most functions you would need on most all the time with a good selection options.

4.3 is better. It's good! It is NOT great.
How "good" can auto-tune be??.. This thing helps, but EVERYONE is going to KNOW, you are using auto-tune. So, like, what's the point?? It might give you the "edge", that little extra COURAGE to get up there and do it. IT IS GOOD FOR THAT then, if that is the case! Yes, it corrects well, but you can definitely tell. The reverb sounds too dense, no matter what the setting. The delay is pretty decent I guess. Tap tempo works great to change it between songs on the fly. Live, this may be really helpful. NOT very great for recorded tracks where you WILL hear this thing in action. (not a good thing). Price is not bad for the number of features! Has 24V boost. Works with Instruments and vocals. Has XLR, and 1/4 in/out. Pretty good in terms of value. I'd get it, if you are a beginner, just starting. YEP!

Algorithm is really bad. Degrades vocal quality.
Really not that good. Sounds bad. Pitch correction results in strange phasing/chorus effects in voice. Even with effects turned down, it still impacts vocal quality- making the voice sound like it’s coming from behind a blanket. Don’t waste your money on this if you are using it for singing in front of an audience or congregation. Might be fine if just for yourself,

Extremely Professional
This vocal effects pedal is super awesome! It includes a delay effect, reverb, and a vocal correction knob. All of these things are top notch. There are multiple default settings you can turn the knobs to which gives it a more fuller sound. And the correction is a game changer. It doesn't work perfectly, but it definitely gets the sound you want. It also makes your voice sound more studio finished, making it great for recording music. I recorded an entire demo in my garage with this pedal and it sounds amazing! I 10/10 recommend to anyone wanting to step up their home recordings.

Delay, Reverb, and Autotune in a box... but it has problems
PRO: -lots of features in one piece of kit. -includes own power supply. -delay and reverb worked great for me, but not why I bought the product. CON: -Correction/Autotune did not really appear to work on my unit at all? -Hidden menu concept: this is annoying as heck. Having 1 foot switch that needs to be double-tapped (unreasonably) quickly to turn off correction, vs single-tapped to... do something else? Or Held to get to the Hidden menu to set the Tempo? OH and then the Correction knob sets the Feedback to the Reverb??? All this is dumb. Just put a few more knobs on it, instead of a big fancy logo. 1 switch for tapping, 1 switch to turning effects on and off, and 2 more potentiometers for settings. Done. -HUGE NOISE FLOOR PROBLEMS. So noisy. Made my mic sound significantly more static-y compared to plugging it into my mixer directly. I couldn't believe it. I spent a few hours messing with settings in the FV01 as well as the Mixer, adjusting Gain, trying different cables and power supplies, nothing helped. I'm returning the FV01 Corrector because it is too noisy for my setup, and I can't use it.

So far so good...
I am a singing bassist in blues and classic rockish bands. I play professionally, but I am not a "gifted" singer. I've had TWO TC Helicon Mic Mechanic IIs. Both fried out on me. (I got the 3-year warranty on this one) This is my initial use review, which I will update as needed. A. You'll want to turn the gain WAY down. The primary "purpose" of this pedal is as a microphone pre-amp. All other features are built around that purpose. I used a tiny flat head screwdriver, but maybe a thumbnail would work in a pinch. B. As with other 'other pedals' the soundvoard should be zeroed out. Tone has zero/warm/bright. The tone does not turn off by action of the foot switch. C. Effects. I use about 15% plate reverb. That's it. The echo and reverb effects all operate as expected. D. Pitch-Correction. I sing the blues, and a few Rolling Stones songs. I'm not Jason Mraz. With the gain and all other factors dialed in, even at 100% I did not detect any artificial sounding corrections. I usually keep it at about 25% and everything sounded very solid. I didn't have to "push" my vocals as much. If I ever get a real singer to use it I'll let you know what they say. E. Foot switch. Green, everything is on. Red, Pitch Correction off, effects on. Tap it twice, No effects, no auto tune, but the TONE stays (which is not an issue- I just don't want echo/reverb when I'm talking to the audience.) In summary, this is a solid pedal. Turn the gain down, and if you get noise switch the ground and/or switch phantom power. Solid pedal so far.

FLAMMA FV01 Vocal Effects Processor Pitch Correction Voice Pedal
It is a great vocal preamp and having both reverb and delay is great and it is a solid piece of equipment. The small size is great as I can keep in right next my multi track. The different warm selectins is nice. I don't rum my guitar through it as I have an acoustic amp. XLR in and outs is great for low noise level, so this unit has a variety of capabilities. I don't use the voice correction but it is yet another nice effect making it a variety of effects when you add it all up. I also think it is fairly priced.
