Ian Bell’s REDD EQ project is a recreation of the EQ section of consoles bearing the same name, found in Abbey Road Studios in the ’60s. Although the original REDD consoles were tube-based, the EQs themselves employed passive LC (inductor-capacitor) filter networks. RuffRecords’ circuit contains no makeup gain, which will have to be provided by the builder (RuffRecords offers a “Poor Man’s Tube Gain Makeup” PCB as an option). Although the project was intended for use in a traditional 19″ enclosure or as a custom console module, its design bears the 51x/500-series footprint in mind, and can be adapted to that format using a 500-series L-bracket.
