Big Blue Limiter is a character limiter. It is neither transparent nor intended to be. In fact it adds a little mojo to everything you run through it, if desired even when no limiting is taking place.
Big Blue Limiter uses analog tube modelling in its limiting circuitry, which makes any limited warmer and fatter by adding a pleasing amount of coloration.
In addition, this plugins also comes with an independent preamp you can easily overdrive.
Whenever your material lacks character or oomph you will find that Big Blue Limiter is exactly what it takes.
