Hey Ham_Phist,

Check out the LM386 datasheet link - it has some sample circuits.  It shows three scenarios for the pin 1 and 8 connection:

* No connection = Gain of 20
* 10uF cap alone = Gain of 200 (!)
* 1.2K + 10uF in series = Gain of 50

So a 1K pot in series with a 10uF cap would allow you to go from a gain of about 50 to 200.  Try it and see what you get.

NOTE:  I messed up the polarity of the cap.  The + side should go to pin 1 of the LM386.  I changed my post above to correct that.
