Right now its running off a 9v battery, haven't seen if the behavior is 
different with other power sources. Also, I put up a different sweeping sample 
that gives a bit more information about the states it goes through as you turn 
the knobs.  I would put up some oscilloscope readouts, but I'm having trouble 
finding software that will show an XY plot in line mode (the dots aren't so 
descriptive in a still) If anyone makes one, I would love to put it on the 
site.
