A HIGH FIDELITY, DUAL PASSIVE & ACTIVE 6-BAND DISCRETE MIX AND MASTERING EQ The CEQ is a fully hand-built, inductor based discrete equalizer using true 'Western Electric' era inductor design, expanded and adapted Pultec passive resonant shelves & boosts along with a novel tailored active midrange cut circuit that adjusts not only frequencies but also the reactivity of sound in a big and gentle way. All inductors are custom wound using 'powder core' toroids, and aren't available anywhere else. The selectable output transformer is sourced from a legendary 'rogue' winder from the 1960's (in Chicago) who makes these uniquely for the CEQ. The CEQ approaches equalization in a unique 'exploded' way while still using classic tried and true filter design topologies used in traditional 50’s outboard equalizers and 60's and 70's mastering filters. An amazingly wide variety of tone can be accomplished rather easily - and while amazing for tracking, the CEQ was tuned in and optimized for placing on the stereo buss for 2-track mastering and the 'essence of the record' while mixing.
