Hartman Electronics Envelope Filter

Envelope Filter Attention: needs 18VDC Center Postiv 2,5mm Connector !! Inspired by one of the great envelope filter pedals of the 1970"s and developed with guitarist Mark Karan (Delaney Bramlett, Bob Weir & Ratdog, Jemimah Puddleduck) the Hartman Envelope Filter is a recreation of a classic effect optimized for tone, flexibility, and ease-of-use. "Mark wanted a pedal with a certain tone, range, and feel that could be switched fluidly among its settings via a simple user interface, and of course, analog.” says Hartman. “I was intrigued by the idea of tailoring a faithful recreation of the Mutron to his requirements, so we set to work. The result is a beautifully voiced musical effect that preserves the raw immediacy of first-generation analog.” (Karan photo at left by Alan Hess. Copyright 2010 www.alanhessphotography.com) 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.
