I'm a newbie to playing the guitar. It was a hand-me-down from a relative and I have recently changed the strings. Every string works fine except the low E string. It's somewhat loose. When I tighten the string, it rings a higher note than the low E. When I loosen the string, it becomes too wobbly to produce a clear sound. Any ideas on how to fix this? Thanks!
I definitely agree that your guitar is tuned to E but a few octaves lower than it should be.
If you are unable to visit a guitar shop or someone to help you I would suggest listening to the sound of someone tuning the E string to hear that it is the correct pitch:
If your issue then still persists it could be a "hardware" issue, which is highly unlikely if your 5th string 'A' is not giving you any issues.
