GGain

I think I've been using this little plug-in for almost 10 years. It is very useful for me when I want to make a channel louder or quieter without using the channel fader. You can set a range between + / - 12 dB and the nice thing is you can also type in the value. It also displays clipping or when clipping has occured. It's very simple but it's been in my inventory for so long now and i would miss it a lot.
