Hartman Electronics Envelope Filter

The Hartman Envelope Filter employs select, low-noise components for its signal path and an optically controlled state-variable filter for authentic timbre and response. A second foot switch permits change of filter sweep direction for on-the-fly access to a broad palette of classic filter sounds from funky chirps and saturated quacks to subtler flute-like attacks and horn-tones. An active Mix control blends filtered and unfiltered signal. Factory preset internal trim pots permit additional tuning of filter action.
