Hartman Electronics Announces Envelope Filter

Inspired by one of the great envelope filter pedals of the 1970s and developed with guitarist Mark Karan

Berkeley, CA (October 1, 2010) -- Inspired by one of the great envelope filter pedals of the 1970s 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 Karan is best known for performing with the extended Grateful Dead family, beginning in 1998 with The Other Ones, and as lead guitarist in Bob Weir & RatDog for the past 12 years. Mark currently tours with his own band, Jemimah Puddleduck.

Mark’s debut album, “Walk Through the Fire” was released in 2009 to critical acclaim featuring special guests Delaney Bramlett, Bill Payne, Mike Finnigan, Pete Sears, John Molo, Hutch Hutchinson, The Persuasions, The Rowan Brothers, and many more.

“Mark wanted a pedal with a certain tone, range, and feel that he could switch 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 old Mutron to his requirements, so we set to work. The result is a beautifully voiced, touch-sensitive musical effect that preserves the raw immediacy of first-generation analog.”

The Hartman Envelope Filter employs select, low-noise components and an optically controlled state-variable filter for authentic timbre and response. A second footswitch 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 voice and action.
