Noisebud Binvert takes the signal and splits in into two bands (split point is adjustable between 20-400Hz).
After the split we put in a phase invert for both bands so you can invert the polarity of the two bands independently from each other. Problem fixed, the bass is still heavy and the mid/high transients stay crisp.
But it is a Noisebud plugin so we couldn’t just make a boring tool, we attached a resonance control  to the filter that isn’t really supposed to be there at all but it’s fun. We use it to self oscillate at low frequencies so it becomes a bit of a bass-drum-low-frequency-replacer-plugin…
