The bx_subfilter is a nice and handy tool to beef up your low end -- super simple but effective. I just used it to give a bit more oomph to one of my ongoing projects. No brainer!
Taken from the awesome bx_subsynth this cheeky little bottom end exciter really enhances the subs in what ever you stick it on! You'll have your neighbours complaining in no time.
This feels like a van load of extra sound just turned up at your mix and added an extra octave. Brainworx -- worrying bassbins since 2017.
