I recently purchased a six string bass and after having only played on a four string, muting is a bit tricky. Before, muting the strings I wasn't using wasn't a problem a all, in fact I never thought about it while playing and practicing. Now that I have 2 more strings, I find it rather difficult to keep all strings but the ones I'm currently using muted. Any time I'm practicing and I hear lots of extraneous string noise from the ones not being used. Any tips on ways to minimize this and how to practice string muting?
