I found , not too long ago that the jack socket that I talked about in the last review did not have an issue and that the loose connection came from the cable I was using and tried another cable to test and prove the theory so l am please that the jack socket works just fine and I am not having any serious problems with it. I am planning to have a setup which should further enhance the bass's performance.These are really great basses so if your looking for one and are thinking about buying one, go for it, they are a definate investment!
