What Pulse Techniques does

Pulse Techniques, LLC, headquartered in Fort Collins, Colorado, manufactures the complete Pultec line of professional audio equalizers to original design specifications dating from 1953. The company was revived in 2000 by Ph.D. Electrical Engineer Steve Jackson, who spent 10 years conducting electrical, mechanical, and chemical characterization to faithfully recreate the original circuits developed by Eugene Shenk and Oliver Summerlin. Products are organized into three main families: classic tube equalizers (EQP-1A, EQP-1S, EQP-1S3, EQP-1A3, MEQ-5, EQH-2) at MSRPs from $3,795 to $5,295; mastering versions with 21-position ELMA stepped controls (EQM-1A, EQM-1S, EQM-1S3, EQM-1A3, MEQM-5) at $3,595 to $5,295; and solid-state variants using exclusively licensed API 2520 op-amps. A 500-series module line (EQP-500X, MEQ-500 at $1,495) addresses project studios and mobile recordists.

The core technology centers on passive equalizer circuits using inductors and capacitors for boost and attenuation curves, paired with either vacuum tube line amplifiers or solid-state API 2520 op-amps driving Triad output transformers. Pulse Techniques is the only company licensed to use genuine API 2520 op-amps. Products deliver a signature sonic character described by professional users as providing "thickest lows and smoothest highs and mids" with unique simultaneous boost and attenuate capabilities at similar frequencies.

The business model is one-time hardware unit sales with no recurring revenue, distributed exclusively through an authorized dealer network spanning 20+ countries including anchor partners Sweetwater, Vintage King Audio, and Front End Audio. The company sells to professional recording studios, mastering engineers, film/post-production facilities, and project studios, with an endorsement-driven marketing approach featuring 25+ named engineers including Bob Clearmountain, Chris Lord-Alge, Dave Cobb, Jack Douglas, Eddie Kramer, and Vance Powell. The company is founder-controlled as an LLC with no disclosed institutional funding or parent company.
