Tonelux, who told me and Patrick Kunz (Togu Audio Line) to change the name, have released this (AWESOME) equalizer. It's been out there in plugin form for about a year. And the center freq is adjustable making it little more versatile. I know some Sound on Sound writers just love tilt eq's so they should love this plugin. Just VST and AU though, but it works with a wrapper. Go get it here: http://kunz.corrupt.ch/?Products:VST_TAL-USE
Did I say it's free yet?
I always hoped that some plugin developer would pick it up one day, and when I contacted Patrick he was great. He build this in days!
It's called USE these days (ultra simple eq)
I'm not sure how practical/useful the EQ is going to be, however I can see myself using the equally free TAL-DUB-II delay quite a bit.
