Vst - Camelcrusher

It is arguably the most popular tool for adding "growl" to 808 sub-bass.

Try this chain on a boring 808: CamelCrusher (Tweak distortion: 10 o’clock, Compressor: 2 o’clock, mix: 30%) -> EQ (boost 60Hz, cut mud) -> Another CamelCrusher (just the Mechacomp at 50%). You will shake the room. camelcrusher vst
