The FC11 Envelope Filter pedal is a mini form factor pedal from Flamma Innovation featuring a robust and customizable envelope filter for auto-wah style effects. Unique to the FC11 is its pure analog circuit that provides a warm and natural-sounding effect. Featuring a wide range of knob controls, users can set up their FC11 to be used with guitar or bass and cater their tone for a variety of different styles using the Sensitivity, Tone, Decay, and Q knobs. True bypass is also included to prevent unwanted signal degradation when the pedal is off. The FC11 is housed in a durable metal shell with one of the smallest footprints on the market fits easily on any pedalboard.
