Notes: MSRP per manufacturer site, verified July 2026. FLAG: manufacturer's own product page gives only a general description ('feed-forward and feed-back control... virtually infinite compression range'); the PWM gain-control-element topology and detailed control list (threshold/ratio/attack/release ranges, sidechain HPF) are corroborated from third-party dealer/review pages (Sound on Sound, Tape Op, Vintage King) rather than stated in that level of detail on greweb.com itself. Single 500-series slot, powered by host rack.
