Electro-Harmonix MICRO Q-TRON – effects pedal

The Electro-Harmonix Micro Q-Tron is a dynamic envelope filter pedal that adds classic auto-wah expression to guitar and bass with modern clarity, fast triggering, and an irresistible musical sweep. Based on the legendary Q-Tron line, the Micro Q-Tron offers a touch-sensitive filter that opens and closes according to the intensity of your playing, creating funky quacks, vocal vowels, and rhythmic movements perfect for funk, fusion, jam bands, neo-soul, and groove-oriented styles.

With the three-position switch – Low Pass, Band Pass, and High Pass – players can adjust the filter's character from warm and round to sharp and biting. The DRIVE knob sets the input sensitivity, ensuring the filter responds accurately to humbuckers, single-coils, or bass pickups. With its smooth analog filter curve, the Micro Q-Tron retains low-end definition and adds expressive movement to both clean and lightly overdriven sounds.

Compact, responsive, and full of organic character: this is one of the most versatile envelope filters available for players who want an iconic funk tone in a pedalboard-friendly form.
