The best equalizer for vintage sound and high-end space.
I really like this equalizer for its ability to give a very clear-sounding high end to my recordings. I put it in my master chain and have great success with it. There is a lot of character in this EQ but the best part for me is the high-end space it provides. The low end is good too with some tonal character in the lower tones that gives a great analog feel to my recordings. You can do a lot with this equalizer but I have only used it, so far, for un-muddying my tracks and it works wonders for me.
