I have an A5 humbucker that's too shrill and piercing. So I swapped the magnet for a rough cast A2. It's better, but not quite where I want it to be. The highs are smoother and the mids are more prevalent. If I want the highs even more rounded, what's the next step? The original magnet was 1/4" shorter than the new one. Will shortening it help? Is there a way I can make the new A2 a little weaker?
