re: the strip on the back, that looks like "CGCDF#D 12-3-4-5-2 FMC tuning" (feel free to correct me if you see something else) -- I remember wondering about this when I took the picture, but never really figured out what the "FMC tuning" might refer to...

here's the direct link to the guitar's page:

http://www.sonicyouth.com/mustang/eq/gtr68.html

so you can see where it's been used within sonic youth. i'm sure he's used it for some other shows/projects too, but what's FMC...? any theories?

Too worn to be reminder for new song that they are writing?

I know he has used this guitar with text of light, but I don't know if that has anything to do with "FMC"

I think the tape says CGCDF#B.
