Hello , Since i am totally newbie i would ask for a help. I don't have a cable atm , so i am practising my bass ampless. It's quite silent and i can barely hear a string if i don't use my fingernail to pick it. So , i noticed that when i want to play something , i press the string with my left hand and pick with right. But , i don't get a "good" sound , i just hear a good tone and in the same time i hear some buzzz noise because my string is touching the fret. Is it normal?(Common when playing without an amp) Or is it broken?
