Hi, people. I have just started playing bass, not 2 weeks have passed since I began and what worries me most is the scratch noise I produce when I move through the fretboard. No matter if it's the same string. I don't know if I make myself clear. It's like my fingertips get stuck into the string and when I want to shift to another note, I produce this noise. It's like I slide instead of release the string. Your advice or comment will be very much appreciated. Cheers.
