SoftDrive GV Free distortion VST

SoftDrive GV Free distortion VST plugin effect

SoftDrive GV is a free VST virtual-analog model of the Marshall “Guv’nor” and “Guv’nor GV-2 Plus” guitar distortion effects.


The Guv’nor is a solid-state distortion pedal first issued in 1989 to recreate the sound of a cranked up Marshall stack in a small stomp-box format. It became rather popular in the 90’s and is still used widely nowadays for its quality high-gain sound and a its tonal versatility. It was re-issued in the early 2000 in an updated housing and incorporating a new “Deep” control to mimic the effect of a JCM2000’s “Deep” switch.

This VST model is a tribute to the original effect and models the circuits of both the “vanilla” Guv’nor and its modern GV-2 variant.

SoftDrive GV expands on the original design and brings in new possibilities unthinkable of outside of the digital realm.

The Model

The overall effect structure is as follows:

  • Input Filter
  • OpAmp A (gain, filtering, clipping)
  • OpAmp B (gain, filtering, clipping)
  • ToneStack (LED clipping, filtering)
  • Deep circuit (filtering)
  • Output Filter (attenuation, filtering)

Each stage is modeled separately and using different techniques. A care is taken to make sure that no inter-stage dependency is lost during the decomposition.

The input filter is a simple high-pass filter digitized with Bilinear Transform.
