Well the last time I heard a Dim D was sometime in the '80's and I don't remember what it sounded like firsthand. I remember it from the Gabriel CD's. This plug is great. As a stereoizer it's amazing. So far totally stable in Reaper,Win XP2, .5% cpu use. The choruses are very lush yet transparent and they sound huge! Made me play guitar through it for an hour just exploring. Very '80's sounding but in a great way! A must buy for me!
