My first post on the Bass Place, so I apologise if this has been covered ad nauseum. My bassist has an EB type Epi that he loves to play but suffers from the ongoing complaint about the clarity of its sound. On the guitar forums there is a fix that involves a cap in series with the offending pickup that is highly recommended for removing mud from the signal. Will this work on a bass and, if so, what value is recommended? I'm sure that there are pickup upgrades that will help, but we are not starting down that rabbit hole...., Yet. Any information would be greatly appreciated and thanks for listening.
