OOPS! Should have posted this in the main forum! Posted it new there.

Well, I built my first Headphone amp. Used the GEM schematic but I have 2 questions.
1. The distortion isn't really that good. I'd like it to be more like a FUZZ, but not sure what to do. I put the 10uF cap between pins 1 & 8. Can this cap be eliminated or changed to differnet value to get a better distortion?
2. I'd like to add an AUX IN jack for my MP3 or CD player. How would this be done?
Thanks,
Scott
