I'm voting the treble knob is turned up too high. My guitarist has a pretty nice MM or Sterling 4 string with active pre-amp and passive/active toggle.. and I was getting more clickity clack than i was used to last time I was playing it. Rolling the highs off a bit on the bass got rid of it. P.S. the bass I mentioned has a wonderful setup, feels great to play, just really sensitive to string noise when the treble's boosted too much.
