The Flamma FC11 is a pocket-sized envelope filter and dynamic auto wah pedal from Flamma Innovation, designed to produce auto-wah style effects that respond to how hard you play. It is a mini form factor pedal, housed in a durable metal shell, and it runs on a pure analog circuit. Flamma Innovation says that circuit provides a lush, warm sound, and Pedal of the Day's review described the result as a warm and natural-sounding effect12.
For players exploring filter pedals alongside a wah-wah pedal, an envelope filter is the touch-sensitive alternative: instead of rocking a pedal, the filter sweeps automatically based on your picking dynamics.
Controls
The FC11 keeps things simple with four knobs and a footswitch. Flamma Innovation says the Sensitivity, Tone, Decay and Q knobs allow you to set your favorite tone, and Pedal of the Day noted they let players cater their tone to a variety of different styles12.
| Control | What it does |
|---|---|
| Sensitivity | Sets how the filter responds to your playing dynamics12 |
| Tone | Shapes the overall tone12 |
| Decay | Shapes the filter's decay behavior12 |
| Q | Shapes the filter's Q, the character of the wah sweep12 |
The Sensitivity knob is the one to reach for first when moving between instruments, since the filter's response depends on the strength of the input signal21.
Guitar and bass
Flamma Innovation lists the FC11 as suitable for guitar and bass, and Pedal of the Day's review said users can set up their FC11 to be used with guitar or bass12. That makes it a candidate for players browsing bass pedals as well as guitarists, since envelope filters have long been a staple on both instruments.
Size, build and price
The FC11 is a mini pedal, and Pedal of the Day highlighted its footprint as a selling point2:
"Housed in a durable metal shell, with one of the smallest footprints on the market, the FC11 Envelope Filter fits easily"
That small footprint matters on crowded boards, where a full-size envelope filter can crowd out an overdrive or delay. On price, Flamma Innovation's product page lists a regular price of $59.90 USD, with a launch price of $39.90 USD, as of October 20261.
What reviewers said
Pedal of the Day reviewed the FC11 in February 2022 and came away favorably, calling it a mini-sized gem and praising the analog circuit's warm, natural-sounding effect2.
"Cheers as always to Flamma Innovation on another mini-sized gem"

Questions
Is the Flamma FC11 analog?
Yes. Flamma Innovation describes the FC11 as a pure analog circuit, and says that circuit provides a lush, warm sound. Pedal of the Day's review likewise noted its pure analog circuit and described the effect as warm and natural-sounding, which matters to players who prefer analog filtering over digital modeling in this kind of dynamic wah design.
Does the Flamma FC11 work with bass?
Yes. Flamma Innovation lists the FC11 as suitable for guitar and bass, and Pedal of the Day's review said users can set the pedal up to be used with either instrument. The Sensitivity knob is the control to work with when matching the filter's response to your instrument's output.
How much does the Flamma FC11 cost?
Flamma Innovation's product page lists the FC11 at a regular price of $59.90 USD, as of October 2026, with a launch price of $39.90 USD shown on the same page. It is a mini-format pedal, so it takes up little room on a pedalboard relative to its cost.
What does the Q knob do on the Flamma FC11?
The Q knob is one of four controls on the FC11, alongside Sensitivity, Tone and Decay. Q sets the resonance of the filter, which shapes how pronounced and peaky the wah effect sounds as it sweeps. Together with the other three knobs it lets players tailor the envelope filter to different styles.
