Ardour3, a drum loop and a plugin, and what happens when you put them all together:
I love it. Use it all the time.
What a great example, the way that Kick cleans up once you take away all those flabby lower mids (250-400Hz) which seem to plague a lot of mixes sells the plugin right there IMHO. For fun I’ve run the PEQ-2 on a few professionally mastered big-name songs and even there it really shows it’s stuff.
