No other overdrive or distortion circuit can do what a Lang OD and boost pedal can.
Other pedals have circuits that can change diodes and clipping circuitry but only the Lang OD can adjust from clipping at the power rails to the zero crossing for each half of the signal.
The Lang OD pedal can be adjusted for symmetrical or asymmetrical clipping at any level from the voltage power rails to the signal's zero crossing point
This allows the guitarist to adjust the dynamics and the even and odd harmonics separately from the drive/ gain control.
