Inspired by one of the great envelope filter pedals of the 1970's and developed with guitarist Mark Karan (The Other Ones, Bob Weir & Ratdog) the Hartman Envelope Filter is a recreation of a classic effect optimized for tone, flexibility, and ease-of-use.
In addition to authentic timbre and response, the Envelope Filter's second foot switch permits changing the 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. Active Mix control blends the effect output signal with dry for subtler applications.
