SPRES (also known as Catharsis) has continued to live on. Not just in our hearts but on hundreds of records and a few different plug-ins. Now you can officially get your hands on the Impulse that changed heavy guitars forever. This plug-in also includes a new impulse designed by Ryan Harvey and Antonio D’Aquino to compliment the original in the best of ways! It also has some eq and some other shit going on. It’s rad and makes guitars sound better.
