The Flamma FC05 Mod is a mini multi-modulation pedal from Chinese builder Flamma, a relatively new name in the stompbox world, that puts 11 modulation effects into one small, bright green box1. Instead of buying separate chorus, flanger, phaser and tremolo pedals, a player gets all of them, plus some more experimental modes, on one spot on the pedalboard.
Flamma's own product page lists the FC05 as sold out, and the related FS05 multi-modulation pedal is also listed as sold out, as of October 202623. The maker is not currently selling either unit.
Eleven modulation effects in a mini pedal
The FC05 offers 11 effects, running from the all-time classics to more unusual territory1:
That list means the pedal covers the modulation types most players reach for first, including chorus, flanger, phaser, tremolo and vibrato, plus filter-style Auto Wah and experimental modes like Ring and Low-Bit. Pedal of the Day described it as a pedal that "crams elements of chorus, flanger, phaser and more into its bright, shiny green box"4.

The JHS Pedals blog highlighted the range too, noting that the pedal holds standard modes alongside ring modulation, and encouraging players to step outside their comfort zone with the more unusual options5.
The controls: Speed, Depth and Ctrl
Three mini knobs control the pedal: Speed, Depth and Ctrl1.
| Control | What it does |
|---|---|
| Speed | Sets the speed of the effect1 |
| Depth | Sets the depth, controlling the intensity of each effect14 |
| Ctrl | Sets one mode-variable setting, a parameter that changes with the selected effect1 |
The Ctrl knob is the one worth understanding. Because it adjusts a single variable that depends on the active mode, its function differs from effect to effect rather than doing one fixed job1. Pedal of the Day described the speed and depth controls as handling the speed and intensity for each effect4.
How it differs from the FS05
The FC05 is a stripped-down version of Flamma's bigger FS05 Multi Modulation pedal. According to Pedal of the Day, the differences are short: no stereo connectivity, no presets and only one Ctrl knob, and those are "about the only differences between this FC05 and the bigger FS05 Modulation pedals"4.
| FC05 Mod | FS05 Multi Modulation | |
|---|---|---|
| Effects | 11 modulation effects1 | 11 modulation effects, classic to experimental3 |
| Presets | None4 | 7 storable slots6 |
| Stereo | No4 | Yes, stereo modulation effects3 |
| Controls | Speed, Depth, Ctrl1 | Per-mode controls1 |
Flamma is described by Delicious Audio as "a rather new player in the stompbox realm"1. The FC05 sets itself apart in the modulation line with eleven modes: Chorus, Flanger, Tremolo, Phaser, Vibrato, Rotary, Liquid, Auto Wah, Stutter, Ring, and Low-Bit1.
Size and build
Flamma describes the FC05 as tiny, durable and portable, housed in a full metal shell2. Delicious Audio noted its "good-mood-inducing bright green case"1, and Pedal of the Day called the shell sturdy and durable4. For a player building a compact board, the mini format means the 11 effects take up roughly the space of a single standard pedal.
What reviewers said
Delicious Audio's take was practical: if you like the sound in the demo videos and need a do-it-all modulation pedal with a small footprint, the FC05 is a good fit1. Pedal of the Day reviewed it as part of a series of Flamma coverage and found the range of 11 modulation types the main draw4. The JHS Pedals blog writer admitted a soft spot for it, saying "The FC05 Mini Mod holds a special place in my heart"5.

Questions
What effects does the Flamma FC05 Mod have?
It carries 11 modulation effects: Chorus, Flanger, Tremolo, Phaser, Vibrato, Rotary, Liquid, Auto Wah, Stutter, Ring and Low-Bit. That range runs from everyday modulation types to more experimental ones like ring modulation and low-bit, so one small pedal covers a lot of ground.
What does the Ctrl knob do on the Flamma FC05 Mod?
The Ctrl knob sets one mode-variable setting, meaning it adjusts a parameter that changes depending on which of the 11 effects is selected. Alongside the Speed and Depth knobs, it gives each effect three adjustable controls in total.
Is the Flamma FC05 Mod sold out?
Yes. Flamma's own product page for the FC05 lists it as sold out, and the related FS05 multi-modulation pedal is listed as sold out too, as of late October 2026. Secondhand listings may still be found, but the maker is not currently selling it.
What size is the Flamma FC05 Mod?
It is a mini pedal in a bright green case with a full metal shell. Flamma describes it as tiny, durable and portable, and reviewers have noted the sturdy metal construction, so it suits players building a compact pedalboard.
