List of available EQ's:
Standard Digirack EQ's: no feedback on the interface yet very transparent.
Digi EQIII: also very transparent and a high quality EQ.
Waves Qnn: an every day EQ, transparent and good interface.
Waves RenEQ: A little colored, decent interface.
Bomb Factory Pultec Bundle: Excellent tube emulation EQ (my new fav!) Subtle and simple.
Izotope Ozone 3: Nice interface with spectul meter in the background. Transparent and a lot of control (second fav).
Waves Linear Phase Broadband and Lowband EQ: Steep LP and HP filter curves with good control. Lowband is good to eliminate low frequencies when they are not needed.
T-Racks... Absolute junk! (IMHO) Very colored and inaccurate interface.
Waves has a totally corrupt policy called WUP that I in no way support. If I did it all over again, Waves would be the last company I would support by giving them my hard earned money. Being a hobbyist, Waves is now a liability rather than a tool. I will not instantiate Waves in any new projects. $2K absolutely wasted! Worst money I've ever spent!
I will give the Pultec a "buy" rating if you can get it for a good price. I got mine for $12.50 in the limited time ProTools LE
v7 plus upgrade program. I wouldn't pay MSRP for it.
I give Izotope a "Best Buy" as the plugin is SO VERSITILE for the money. Their 64bit bundle is a steal at $299-/street price.
Do you want to see your EQ working? Get the Elemental Audio Inspector XL. Awesome metering for only $89-. Good folk to deal with.
