Sorry for my ignorance guys, but I seem to be having a major brain fart this morning. I can't find the equalizer in iTunes 9.2 on Mac OS 10.6.4. The only way of using the equalizer is to select songs and than type command+i. Then under the 'options' tab you can select an equalizer preset. Didn't there used to be an equalizer that played the entire music library using one preset? And couldn't you specify your own values for the different frequency bands? Thanks for the help.
