I use this eq for everything. It is the best sounding Eq in my VST folder. It sounds so nice, you can boost the high end and it still sounds silky smooth, you can boost the bass and it doesn't get muddy, it sounds tight and defined. The developer says it emulates a transistorised eq to color the sound, but I find it still sounds very transparent and smooth, it doesn't have that exaggerated sound like some plugins that try to emulate "analog warmth".
This sound quality comes at a price. Poshifopit can use up some CPU, but it's really not bad for the sound you get. I took me a while to realize you can disable individual bands, that will help some.
Poshifopit lacks the dials and sliders of most software eqs. It seems most of the innovative plugin developers are breaking free from a "looks like hardware" interface. Personally I think this is a move in the right direction. I find poshifopit easier and faster to use. I absolutely love the gui. Instead of knobs, Poshifopit has one "point" per band on a horizontal line. You drag the point up and down to adjust the level, and left and right to adjust frequency. Right clicking the point changes filter type. You can adjust Q by alt clicking over the point and moving the mouse up or down. This interface allows you to adjust frequency and level in one step very quickly.
The original skin is pretty ugly, but there are other skins included. I use the Fruity Loops skin and it looks great.
This is the best soft eq I have heard. I have not heard any of the really expensive ones, but I wouldn't be suprised if Poshifopit is as good or better than the high end eqs. The best part is the price, it's totally free! I highly recommend trying this one!!
