Rebel Audio has released DoubleToner, a free dual-quad-band distortion effect plugin for Windows.

Rebel Audio DoubleToner

Change some small details or damage your sound beyond recognition. The dual-quad-band distortion concept of the DoubleToner gives you a variety of possibilities to enhance your audio production.

Play with the crossover filter to distribute the incoming audio band on the two independent distortion units. Change the color of the expanded sound with the four analog approximated band-pass-filter units. Use the crossover fader to mix the resulting bands to an individual processed output signal.

DoubleToner is a free download for Windows (32/64-bit VST).
