The Flamma FV03 is a character vocal effects pedal from Flamma Innovation, a pedal that sits between a singer's microphone and the rest of the rig and reshapes the voice with six selectable voice-altering effects, with reverb on hand for polishing up vocals1. It is aimed at the singing guitarist: it also takes a guitar input, with optional guitar reverb effects of its own1.
What it does
The FV03's core job is voice alteration. Flamma Innovation describes it as offering six special voice-altering effects, selectable between them, so a player can move among different character treatments of the vocal rather than stacking several pedals1. Alongside those, the maker lists rich reverb effects for polishing up vocals, covering the more everyday work of adding space and finish to a voice1.
It is built for players who sing and play at the same time. The pedal includes a guitar input with optional guitar reverb effects, so the guitar can be given its own treatment without a second unit1.
At a glance, the FV03's feature set breaks down like this:
| Feature | What it does |
|---|---|
| Voice-altering effects | 6 special effects, selectable between them1 |
| Vocal reverb | Rich reverb effects for polishing up vocals1 |
| Guitar input | Takes a guitar signal alongside the microphone1 |
| Guitar reverb | Optional reverb effects applied to the guitar input1 |
| Output modes | Mixed, or individual guitar and microphone signals1 |
| Phantom power | Optional 48V power over a microphone cable1 |
Outputs and power
The pedal offers two different output modes1:
- Mixed: a single signal combining the guitar and microphone, suiting one feed to an amp or mixer.
- Individual: the guitar and microphone signals sent separately, so each can be handled on its own channel.
For power, Flamma Innovation states the FV03 can optionally be powered by 48V phantom power, the supply carried over a microphone cable from a mixer or interface1. Where phantom power is available, the pedal can run from the mic line itself.
Phantom power is an optional power route, not the only one. The maker's page describes it as an option, so a standard pedal power supply remains a consideration for setups without phantom power available.
Where it sits in Flamma's vocal range
The FV03 is one of Flamma Innovation's dedicated vocal pedals, alongside the Flamma FV01, the Flamma FV02 Doubling Vocal Effects Pedal and the Flamma FV04. Its combination of voice-altering character effects with a guitar input and its own guitar reverb sets it apart from the simpler single-purpose vocal pedals in the wider field, such as the TC Helicon VoiceTone R1 reverb unit or the TC Helicon Mic Mechanic 2.

Questions
What does the Flamma FV03 do?
It is a character vocal effects pedal from Flamma Innovation. It offers six special voice-altering effects you can select between, plus rich reverb effects for polishing up vocals. It also includes a guitar input with optional guitar reverb effects, so a singing guitarist can process both signals from one pedal.
How is the Flamma FV03 powered?
Flamma Innovation states the FV03 can optionally be powered by 48V phantom power, the standard supplied over a microphone cable from a mixer or audio interface. That means it can draw its power from the same cable that carries the microphone signal, where phantom power is available.
What are the FV03's output modes?
The pedal has two different output modes: one that sends a mixed signal combining the guitar and microphone, and one that sends the guitar and microphone signals individually. That lets a player either feed a single combined signal to an amp or mixer, or keep the two sources separate for independent processing.
