Hi Bernier,

Spectrasonics' Trillian VST can do that, easy. Check out the first demo on this page: https://www.spectrasonics.net/products/trilian-audio.php

You could probably get a similar growl out of other bass guitar sounds by adding my favourite saturation/distortion plugin, Soundtoys' Decapitator to the signal chain, but Trillian can do it right out of the box.

Thanks
