On one of my passive basses the little height adjustment screws on the bridge saddles stick up really high. Its where I got the strings really low and where I want them. Downside is when I use a pick the little screws jab into the meat of my hand. So I just took some blue masking/surgical tape and covered up the heads of the little screws. Now I know this sounds like a silly question...But will that tape cause any kind of interference with the grounding of the instrument or any sustain issues? I know this sounds like a silly question but its always those little things you never know about.
