Crossover-like Distortion

Blade Schematic

Blade uses a diode bridge recitifer in the feedback loop of an inverting opamp to create crossover-like distortion. There are five controls. Drive adjusts how much signal is fed into the loop, Depth controls how strong the effect is, Sym (Pos) and Sym (Neg) affects the symentry of the signal by setting the level on the positive and negative sweeps of the signal, and a Level output control.
