The Analogue Filter by Mojo Hand is based on the same circuitry as the original DOD 440, but with a wider frequency range for baritone and bass players.
It is NOT based on the incorrect schematics floating around the internet. The originals are getting hard to come by and the prices are going up accordingly. This one has added modern improvements like an LED and true bypass switching.
