In the Smells Like Teen Spirit Patch on my Pocket Pod(for the distorted part in the chorus), the EQ settings are LOW 78%, MID 100%, HIGH 84%.  I've found that for that really weird tone in the solo, you should set the EQ to LOW 70%, MID 40%, HIGH 30% (these aren't exact, just keep the bass around the 7th notch, mid around the 4th, and high around the 3rd).
