this is a really nice little graphic EQ from SPL and its free.... you'll find yourself using it a lot for quick frequency notching as its got a more neutral character to tis cut than the waves 560 or other API emulations. It also has 1 less band and a number of different frequency centers that work on a wide variety of sources whereas I find the 560 to be very guitar-centric with its choice of bands. The Q on the bands is its own thing and its definitely useful. Another lovely gadget from SPL.... and they're just giving it away! If you have no other SPL plugins you should have this one.
