The Flamma FV04 is a harmony vocal pedal with reverb, made by Flamma Innovation. It is aimed at singers who perform with a guitar: the pedal generates harmony voices for the microphone input and adds reverb, and it can handle the guitar and microphone signals together or separately. It belongs to Flamma's line of vocal pedals, sitting alongside the company's better-known guitar effects such as the Flamma FS02 and the Flamma FC02 Mini Reverb in the reverb family1.
What it does
The FV04's core feature is vocal harmony. Flamma's product page describes it as offering "12 pitches with 11 different harmony modes," which means the pedal can produce harmony voices at different intervals above or below the sung line, selected across eleven modes1. A reverb effect is built in as well, so the vocal carries ambience along with the harmonies1.
For a performing singer-guitarist, the output arrangement matters as much as the effect. The pedal provides "two different output modes for a mixed-signal or individual signal from guitar and microphone"1. In practice, that means the FV04 can send one combined feed to a PA or interface, or keep the guitar and microphone on separate paths so each can be mixed independently.
Price and availability
Flamma Innovation's own listing shows the FV04 at a regular price of $138.00 USD, with a sale price of $168.00 USD shown on the same page1. The page also listed the pedal as sold out as of 26 October 20261.
The FV04 was shown as sold out on Flamma Innovation's product page as of late October 2026, so availability may vary.
