I am a beginning bassist with a dumb question: The way I pluck the bass strings, my finger pushes the string toward the fretboard before release. When I play hard, the strings tap against the fretboard and make a clicking noise that registers thru the amp. Is this an acceptable sound for rocknroll, or do I need to change the way I pluck the string to eliminate the clicking sound? For example I commonly end up making the sound during quick tremolos. Acceptable?
