cmoy question

I've got a question thats probably easily answered. I've got a standard... run of the mill cmoy that I built probably six months ago. The other day I checked the integrity of my virtual ground (just a voltage divider btw 4.7k resistors, no TLE2426) and I noticed that it was splitting uneven (+3.7V -5V). I thought this was odd, but I couldn't tell a difference in sound. Well today I started to tinker with it again (I was going to change out the input caps) and I noticed that the 9V battery was splitting evenly. Then I plugged my headphones in and sure enough it splits uneven again. I was just curious if anybody had experienced anything like this. I really havent had time to draw up a schematic/look at any of them since I stay busy with school... (third year EE student haha).

cliffnotes: virtual ground (just two resistors, no TLE2426) splits evenly with no headphones plugged in, splits unevenly with headphones attached.

Thanks,
Tyler
