From the post
An old german overdrive that has become almost a cult item. It has a very well designed circuit with lots of sensible filtering and a higly tweaked gyrator powered tone control called "Spectrum". Some "bouteek" pedal companies has started making their own variants of this circuit, the most noticable ones are Wampler Belle and Rockett The Dude. I've included the Bass control found in the Aion Fx Andromeda project. Factory schematic is avaiable HERE and Aion Andromeda project files is avaiable HERE.
