So when I got my new P5, the low B was ok, but definitely needed some work. So I sat down and tried to figure out how I could improve it or if I could at all. I played it for a while, then I realized that the low B almost sounded like it had that "Fender A string syndrome", but on the B. The low B was the only string that did not have a string retainer of any sort on it. I also remembered that the low B on the American Deluxe P5 that I used to own was pretty good. So I went ahead and purchased a set of hipshot string retainers, just like those that are found on the American Deluxe 5'ers. Got them in, installed them and DING DING DING!! A ginormous improvement in the low B. I strung the bass back up with the stock strings, but then thought that they might be holding the low B back a little too. So I strung the bass up with a set of Foderas and let me tell you, this low B is killer!!! A night and day improvement over the bass stock!! I was also able to drop the action a little lower too, because the low B doesn't flop around like it did. Only very minor downfall is that there are two tiny holes left on the headstock from where the old string trees were. But they aren't very noticeable and can be filled easily if needed. Anyone who has a P5 or is thinking of getting one, should really consider this $22 mod. Here are some pics: This is the bass before the mod - No string retainer on the low B! Here are pics of the new string retainers!!
