ReaEQ (part of the free reaplugs bundle) with unlimited bands
melda MEqualizer (also free)
The Melda EQ is a very powerful tool with more uncommon features:
AutoListen ON/OFF: As soon as you grab band you'll hear this band only. As soon as you release the mousebutton it switches back to normal listen.
Harmonics per band: Set up to 10 harmonics per band.
Fully customizable (in color and Size) GUI
Set up 4 different EQ settings (A-D) and morph between them with an X/Y pad.
Some of the settings won't stay in memory in the free version tho but IMO thats ok.
