Uneven volume increase when using Volume X

  • I am using a Dunlop Volume X into my KPA Stage and when doing volume swells (after the stack) I am getting a noticeably uneven jump in volume from about heel to %25. I have calibrated the pedal every possible way that I can think of. Has anyone else had this issue? I can do very even volume swells on my other amps with the Volume X so I’m not sure what’s going on. Any help would be appreciated. Thank you!
