With so many excellent delays on the market I wasn't prepared to be impressed, but I was- and that's putting it mildly. Right away you can tell that this delay is tube driven- it is warm, exactly like playing through an old tape delay, but also dead quiet and tweakable. The delays just feel "right" and the "Age of Damage" knob adds just enough "warble" to make you think you are actually playing an old Binson Echorec or Echoplex. The quality of the build, controls, etc. are first-class. I had a hard time unplugging from this unit- it's that good!
