Try Limiter No.6 by Vladg sound. It's free so if you don't like it, no harm done. Toneboosters Barricade is good. It has a free download and it's only twenty something dollars to be able to save settings. I've tried a ton of them, and Limiter No.6 is my main one right now. I plan to buy Concrete limiter so I can have it in the pro channel...for $39, why not?
