I never really notice this during a gig, but in the midst of recent recording I've noticed that my bass has a tendency to resonate a while even after I've muted a note with my left hand...mainly on A string notes, but also on some others. I can dampen this quite a bit if I stick a piece of foam between the top and the tailpiece. Not a problem in the studio, but it'd look goofy on a gig. Anyone have a good solution for this? FYI, I'm using Helicore Pizz mediums on my New Standard Cleveland.
