Again...fantastically helpful responses from people...a brilliant forum. I will definitely look around and to tell the truth I have looked at the Toneboosters because of this thread...hadn't heard of them.
I know everyone will have their effects of choice, and for most of you this is because they work for you, you have taken the time to learn them well and they do what you want them to do. That is the next step for me...to carefully pick some plugins that I will use generically across my music, stick with them until I know them inside out and apply them properly in the mix, instead of always half-trying out loads of toys and their presets.
Thanks again for all the good advice.
