When a guitar pedal starts picking up room noise and vibrating like a cheap microphone, it usually means something inside is broken and ready for the trash. Rainger FX decided to take that exact mechanical glitch and turn it into an intentional, controllable effect. The Microphonic Fuzz pairs a thick, high-gain analog fuzz with a digitally controlled microphone built straight into the enclosure, letting your physical surroundings become part of your dirt tone.
What’s Special About It
The pedal splits its personality across two independent sides. The right side delivers a heavy analog fuzz that stands completely on its own, while the left side kicks on a built-in microphone aimed out the bottom of the chassis. Because it listens to your room, the angle of the pedal, its distance from your amp, and the reflections of the space you are playing in directly shape your feedback. There is even an XLR/TRS combo jack if you want to bypass the onboard mic and plug in an external microphone for different placement or vocal textures.
Most Intriguing Controls
-
Built-In Microphone & External XLR/TRS Input: Captures live acoustic vibrations and room reflections, blending real-world air into your fuzz signal.
-
Dual Filters: Shape the microphone’s frequency response together, letting you tame harsh squeals or push specific resonant feedback frequencies.
-
Square Wave Tremolo: Chops the microphonic signal with hard, rhythmic volume cuts instead of a smooth wave, turning sustained feedback into stuttering pulses.
-
Subtle Flanger: Adds gentle, shifting movement to keep sustained feedback tones evolving organically.
Other Controls
-
Three-Mode Tone Selector: Switches the core analog fuzz between three distinct EQ voicings.
-
Gain & Output Controls: Dial in the intensity of the high-gain fuzz and balance your overall volume.
If you love the unpredictable thrill of standing right in front of a cranked amp on the verge of howling—but want actual control over how that chaos behaves—the Microphonic Fuzz turns the room itself into an instrument.
