Prompted by a Bass Player article on James Jamerson I stuck a piece of foam under my strings next to the bridge. It absolutley rules for tight syncopated funk! For years I had heard Jamerson used a dampener and now I can see why. I have been so caught up with perpetual sustain that it truly opened my eyes to a sustainless feel ala upright. I had no idea somthing so simple could have such an impact on my playing.
