The PSP 2445 EMT immediately found its way into my productions and mixes. My favorite reverbs hug the track in a way that is supportive and not distracting. Using this plug-in feels like I have the EMT units in the equipment room. Rich, complex and dense, this reverb plugin lives permanently in my mix template.
