I hope this works:
A useful tip is to listen first with "bypass all" switched in, to get used to how the songs are supposed to sound without the limiter on.
If you find you need a bit more "bottom end" then lengthen the "low attack" a bit.
If you want a more aggressive sound then reduce "high attack" all the way to the top, or slide the "process" control up towards the "HARD" setting.
It really depends what sort of music you're playing, but I find the sound far too tiring on the ears if the Limiter can be noticed.
I just try to use it to lift the level of quiet songs, and to make "local band" demos sound like they've been "mastered".
I hope this helps a bit.
