Cool, Nick!  I've got a couple of SSM2167 boards, too.

Can you draw up a schematic?  I think I follow what you did, but I want to make sure.

I plan to replace both R1 and R2 with pots.  I'm also going to try to use C3 as part of a HPF by putting another pot between pin 6 and ground.  The goal is to keep everything <300 Hz out of the signal chain.
