I just realised the plugin is a lot more effective with an effect
strength control. A patch against the current caps sources is
attached to this mail (feel free to contact me for help if you don't
know what to do with it).
With the patch applied, you can dial down compression and gain but
still get more bass boost:
lo.f = 240
lo.compress = .3
lo.gain = .2
lo.vol = 20
hi.gain = 0
Cheers, Tim
