Stealing a show I had planned, Jon!

All right, all right. You beat me to it fair and square. 

BTW, there is contact cleaner that is specifically made for music gear and it does contain a lubricant.  Its made by DeoxIT and the line of products is called Fader (Their font choice on 'Fader" looks awful familiar! 

Also, I would say your saturation is not working properly, if at all. That thing should give you all the Hair Metal distortion you could ask for.  :P

You might have a problem with the foot pedal. I had this same issue in the past. You might be stuck in NORM GAIN.  And the pedal is not switching into LEAD GAIN (where the Saturation is).
The problem I used to have is, the 90 degree jack for the foot pedal does not retain/grip the cable in any way. Any tug on the cable can break a solder joint inside. Its something to check out. Its only a couple screws. 

Good luck!  And get some hair spray!
