Nice 'thump', Squeak - it's exactly what I'd love to include in my stuff.

When you say 'sub-sonic', and I don't mean to get into semantics re. sub-sonic's meaning in its literal sense, but what sort of hertz are we talking here, and how do you access and incorporate those ultra low frequencies? I suspect it's more than just taking the bass down an octave or two.

Can you give some insight into that aspect? Thanks.
