anyone have any experiance with these: http://www.sweetwater.com/store/detail/PS04/ my boss has the ps-02 and it was freaking cool. this one is supposed to be better. is it worth it? does it have a ton of options and what not? my boss more or less explained it to me that its an "entire recording studio except for the engineers and all the fancy s*#&". but he had nothing but good things to say. what do yall think?
