Moog Music in Asheville, N.C., announces that founder Dr. Robert Moog will be posthumously inducted in to the United States Patent and Trademark Office National Inventors Hall of Fame. Dr. Moog is being awarded this honor for Patent No. 3475623, more commonly known as the Moog Ladder Filter.
The company states that the Ladder Filter is an essential element of the massive, thick sound for which Moog instruments are renowned. Moog Music created a video featuring Moog hardware engineer Rick Shaich discussing the importance and innovation of this creation. In the video, Shaich discusses the Ladder Filter, the first Voltage Controlled Filter, which is the heart and soul of the Moog modular synthesizers of the 1960s and the Minimoog of the 1970s. Plus, it provides the same filter topology used in all Moog synthesizers to this day.
To celebrate this historic occasion, Moog Music is reissuing the Moog Ladder Filter Tee, which is now available for pre-order and will ship with a free poster commemorating Bob Moog's induction to the National Inventors Hall of Fame.
