Seeing all these posts about vactrols, I have to raise my hand and ask
a few questions. 

1) Which modules are require to get nice 'wooden block' sounds? The
A-101-2? The A-101-9? A combination?
2) How are they used to create such an effect? 

As far as I can tell, the units are combined VCA and filters - that
alone seems to be a combination I can get using... a VCA and a filter.
I'm obviously missing something.

Oh, and happy new year!
