Great for all applications!!
I took a gamble and I picked up the Xfilter Rack for mainly mastering purposes. I was going to dish out the cash for a Dangerous Music Bax Eq because the UBK Clarihonic was not what I wanted until I came across this bad boy.
Plugged this bad boy up into my rig and immediately fell in love. What's great about the Xfilter Rack is that you are able to boost but most importantly you are able to attenuate frequencies without hurting the mix.
So far it sits as my main mastering EQ and has proved its worth over and over. Some mastering engineers might say otherwise but I have done some mastering with this gem and artists have yet to complain.
Definitely a must have tool in your tool box.
