HeadCrusher (Free)

analogue saturation plug-in
For processing individual tracks, the plugin performs very well and it can add a bit of that nice tube like flavor to bass guitars, keyboards, even vocals when used in subtle amounts. It also works well for high gain distortion effects and you can further shape the sound character with the tone knob. The low cut filter is surprisingly transparent and it can work rather well for cleaning up the low end of individual tracks. I certainly didn’t expect to hear such a nice low cut filter and it would be cool to see a dedicated filter plugin from Audio Assault in the future!
