I have just purchased my first electric bass guitar and I decided to tune the strings with an electronic tuner. My question is in regards to noise that is produced whenever I press the strings against the frets and pluck on them. I would describe this noise as a rattling or tapping sound that is a result of metal (strings) hitting metal (frets). It is especially noticeable when I touch the A string because it is loser than the other strings. Is it normal to hear this type of sound? Are the strings supposed to tap against the frets and make noise whenever I play on them? If this is not normal, I appreciate any suggestions. Thanks.
