I recently purchased an electric guitar(no name - nothing grand) and I have tuned it several times and according to the electronic tuner, it's in tune. However, the 'G' string just sounds 'dead' to me compared to the rest. I have not yet found anything in the way of reference that mentions this so I believe this to be my own imagination.

Has anyone else heard of this? What can be done? Replace all the strings?

Thanks-
