Filtron
The Mu-Tron Micro-Tron IV is an envelope filter pedal designed for guitar and bass, delivering the classic auto-wah sound made famous by the original Mu-Tron pedals of the 1970s. It features selectable up and down filter sweep directions, a three-position range switch, and controls for sensitivity, peak, and gain, allowing for precise shaping of the filter response. The Micro-Tron IV is known for its responsive touch sensitivity, robust build quality, and ability to produce rich, funky filter effects suitable for a wide range of musical styles.
