original for kemper Stage and EP1 expression pedal, and it is a perfect fit for those products, I modified the place for the expression pedal, took a knife and cutted out some of the foam where the EP1 should be located, so the Korg XVP-10 pedal got a perfect fit in the case instead of EP1, again good case from Thon cases. needed just som extra glue on foam under the handle.
