Trainwrecked Expresso question

Trainwrecked Expresso question
This question is in regard to the schematic at Steve A's site.  
 
 
 
After the tone stack and vol controls, the signal goes to 1/2 of a 12ax7. After that it "dumps" a bunch of signal (through a 56K resistor) and goes into another 1/2 of a 12ax7. This stage has a cathode resistor of 10K (if I remember correctly).  
 
 
 
What does this stage do? I remember Ken Gilbert saying something about cascading stages using very high cathode resistor values. For instance, I remember Ken saying he cascased 3 stages using cathode values of 10K, 22K, and 50K.  
 
 
 
He said this didn't increase gain, but increased harmonics. Do I remember this correctly??  
 
 
 
Thanks,
