There are two versions of the Immerse Reverberator: the original and Mk II.


  • The Mk II adds the ability to have 100% effect level when the Mix knob is fully clockwise. The original version would only go to about 50%.
  • The Mk II has slightly improved headroom for the wet signal.
  • The Mk II uses a more robust footswitch.
  • The Mk II recessed the Kill Dry and Trails switches to help avoid accidental switching.


Here is a comparison of the effects in the two pedals:
