IIEQ
The IIEQ is a free, fully parametric 10-band equalizer with its own, characteristic sound and low CPU consumption. The 1st and the 10th band are low and high shelf filters, respectively; all other bands are peak filters. It comes in two GUI flavours, so you can freely choose which style suits you and your work flow (note: with some hosts you might run into problems if both versions are in your VST folder. And by the way: right-click on the image and save the dll file in your VST folder to start using IIEQ. Enjoy!)
