Envelope Filter

Based on the 1970s MXR Envelope Filter, rebuilt into a modern enclosure with added functionality. Originally limited to 100 hand-wired units, a high-quality circuit board version launched in 2017 for wider availability.

Threshold sets sensitivity to picking dynamics, Emphasis boosts the resonant peak for more pronounced filter sweep, and an Up/Down toggle (inspired by the Mu-Tron III) dictates whether the sweep starts from the low or high end. Fast tracking and low noise from high-grade analog components.

Works equally well on guitar and bass. True bypass with LED indicator. Hand-wired in the USA.
