Symetrix said it recently noted its 30th anniversary.
The company was founded in 1976 by Dane Butcher. In the early 1970s, Butcher worked as a recording engineer, helping to make the first gold instrumental album, Herbie Hancock’s “Head Hunters.”
Butcher took a job with Greg Mackie at Tapco and learned to design electronics. Six months later in 1976, he started Symetrix in an artist’s loft and former garment factory in Seattle. A surplus electronics store across the street enabled him to manufacture the company’s first product, the SG-1 Signal Gate, and subsequent compressors, limiters and phasers.
