Do you think that anyone but you would notice the difference if you did not replace strings as often as you think you need to?
Unless you are breaking them, they are not "killed" they might not sound the same as they did within the first day but to everybody else you sound the same. I have a friend that has been killing the bass for over fifty years and he has always told me that strings only have about two hours of what he likes to call life in them, then they start sounded stale to him. But I asked him one day after I knew he had took about a six month hiatus. "When was the last time that you changed your strings" and he looked at me with disappointment in his eyes and said about six months. That's when I said. "You sounded just like you had six months earlier". Save you some money and ride them strings out.
