This is one of many decent pultech simulations. It works like a pultechand sounds close enough for my purposes. I am not a big fan of using the pultech as intended as a program equalizer, I tend to use it when I need broad correction in a few bands. For instance this gets a lot of play on kicks that have been comrepssed in parallel with a 160. its my bottom recovery and midrange taming device. I use a couple other pultech plugins in that capacity too but I will generally shoot them all out as they all have varying degrees of 'tubiness' and the curves respond a hair different on each of them. One will generally be head and shoulders above the others in context.
