Guys got a Fender DG4 acoustic guitar yesterday along with a Korg CA-30 tuner. Can someone tell me in detail how to tune the guitar using it? The guitar was sounding alright when I bought it but I was trying to learn how to use the Korg tuner and now one or two strings don't sound as they are supposed to. When I play the second thickest string the tuner LCD displays G#. I am confused. Also should I keep the tuner at 440Hz?
It would be great if someone could post a little guide.
