I was playing guitar pretty much all day yesterday, and so it went a little out of tune every once in a while like normal... but, almost 3 times I think, just RANDOMLY in the middle of a song, my G, B, and high E strings all went out of tune by almost a half step. What could possibly be causing this?
TOO MANY PUPPIES

Soda sucks.

Strings might be sticking in the nut. Lube it with a little graphite from a pencil.
