Evil Sound Lab presents Malefica plug-in

The Malefica is a virtual high-gain distortion guitar pedal based on original schematic.

Malefica Formulae
First of all we have analyzed circuits of ton of guitar pedals to design the darkest, most evil and mystic tone with unique character that would fit a wide range of extreme music genres.
After that, we have made its physical model on the tip of the pen and prepared it with most precise and modern mathematical algorithms.
Finally, our designer has added magical artwork, and that is it! Witchery is alive!

Try this one for free and make sure that we do (not) fable.
And do not forget to check out the audio plug-in presets!
