Review: Adds depth to vocals - Really nice unit. Takes a bit of setting up or perhaps memorising the settings for me. Not gigged with, but used it in practice sessions and gave a bit more depth to the vocals. Bit of a faff having to choose the vocal key, but it does work well when set right. Review: la qualité et le délai de livraison - Très satisfaite ## Features - The Harmony provides 11 different harmony modes to choose from and can comfortably shift between major and minor scales for ultimate pitch flexibility. - The FV04 Harmony is the first effects pedal from Flamma aimed at vocalists and guitarists. It happily accepts guitar or microphone inputs and includes dedicated reverb effects for each. - The FV04 acts as an all-in-one effects solution with the ability to choose between mixed signal or individual outputs to separate vocal and guitar channels. - Support for 48V phantom power is also included as is the option to use the FV04 as a microphone amplifier. - The FV04 runs on the included 9V 500mA power supply and its sleek blue, all-metal shell is gig-ready and built to last. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B09C8GLD7T | | Amperage | 500 Milliamps | | Audio Output Effects | Pitch Shifting, Reverb, Preamp | | Best Sellers Rank | 4,776 in Musical Instruments & DJ ( See Top 100 in Musical Instruments & DJ ) 539 in Guitar Effect Pedals | | Brand | FLAMMA | | Brand Name | FLAMMA | | Colour | Blue | | Connector Type | 1/4 inch audio | | Controls Type | Knob | | Country of Origin | China | | Customer Reviews | 4.0 out of 5 stars 433 Reviews | | Hardware Interface | 1/4-inch Audio | | Included Components | 9V 500mA power supply | | Item Dimensions | 8.6 x 6.1 x 12.4 centimetres | | Item Dimensions L x W x H | 8.7L x 6W x 12.5H centimetres | | Item Type Name | vocal harmony | | Item Weight | 0.8 Pounds | | Item weight | 0.8 Pounds | | Manufacturer | Shenzhen Flamma Innovation Co.,Ltd | | Manufacturer Part Number | FV04 | | Model Name | FV04 Vocal Harmony | | Model Number | FV04 | | Power Source | Corded Electric | | Product Warranty | 1-year guarantee. | | Product dimensions | 8.7L x 6W x 12.5H centimetres | | Signal Format | Analog | | Style | Compact | | Unit Count | 1 Count | | Voltage | 9 Volts | ## Product Details - **Brand:** FLAMMA - **Colour:** Blue - **Item weight:** 0.8 Pounds - **Product dimensions:** 8.7L x 6W x 12.5H centimetres - **Style:** Compact ## Images ![FV04 Vocal Harmony Pedal Vocal Effects Processor Stompbox Voice Mic Harmonizer with Reverb 12 Pitches with 11 Different Harmony Modes All-In-One for Singer and Guirist Singing Recording - Image 1](https://m.media-amazon.com/images/I/71Xt00a6e4L.jpg) ## Available Options This product comes in different **Model** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Adds depth to vocals *by A***R on 27 July 2026* Really nice unit. Takes a bit of setting up or perhaps memorising the settings for me. Not gigged with, but used it in practice sessions and gave a bit more depth to the vocals. Bit of a faff having to choose the vocal key, but it does work well when set right. ### ⭐⭐⭐⭐⭐ la qualité et le délai de livraison *by C***N on 29 December 2025* Très satisfaite ### ⭐⭐⭐⭐⭐ FLAMMA Harmony = a Busker's MIXER! *by S***L on 20 March 2022* FLAMMA Harmony - It's a MIXER, perfect for busking with any amp! This can mix vocal and guitar signal to one output, eliminating the need for two channel busking amps! In the back, a very tiny knob near the power input controls mic volume, and has a great range, be careful! I have two other vocal harmony pedals that "read" the guitar's two or more notes to add harmonies. This FLAMNA Harmony "Select Key" cannot handle complex non-standard scale chord progressions, but those songs are rare. Selecting the key LIBERATES the guitar!! (if you like to embellish while singing). One BUG (a badly considered "feature?") - on power up, the guitar line adds full reverb, so you must hold the switch down to go into "secret" function (LED goes Blue) and dial it out and afterwards, REMEMBER TO TURN THE KNOB TO SELECT LEVEL OF HARMONY VOICES! (Same for selecting reverb level on mic line with long press on LED) Great pedal, an essential for buskers just for the mixer capability alone! Read the manual! Buy it! Buy a spare to lend to beginning songwriters! ## Frequently Bought Together - FLAMMA FV04 Vocal Harmony Pedal Vocal Effects Processor Stompbox Voice Mic Harmonizer with Reverb 12 Pitches with 11 Different Harmony Modes All-In-One for Singer and Guirist Singing Recording - JOYO DC 9V Guitar Pedal Power Supply (800mA -1A) AC Wall Charger Adapter with 4 Way Daisy Chain Pedal Cables (8.8 FT), Compatible for Most Effect Pedals (Tip Negative) - D'Addario Accessories Guitar Pedal Power Supply - DC 9V Power Cord - 9V Power Supply for Guitar Pedals - Pedalboard Power Supply - PW-CT-9V --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hr/products/454579159-fv04-vocal-harmony-pedal-vocal-effects-processor-stompbox-voice-mic](https://www.desertcart.hr/products/454579159-fv04-vocal-harmony-pedal-vocal-effects-processor-stompbox-voice-mic) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-08-15*
