Sorry to say that new strings will make no difference. The Fatfinger does work and sometimes, so well, it removes the dreaded dead spot altogether. If you go the FF route, try different positions across the headstock as this can make a difference as well. I have three basses with dead spots and all were fixed by the addition of the FF. obviously, the extra metal will make the neck more prone to dive, but at least your bass will sound as it should. Goodest of luck.
