VPJR Tuner tuning function does not receive a signal.

[amortguitar]

I recently got an Ernie Ball VPJR tuner second-hand from someone, and everything works great (touchscreen, volume function) except for the tuner. The tuning interface shows up as designed, but nothing changes when I play a string, as if the tuner is getting no signal at all. Has anyone had this issue? I don't think I have any warranty option since I got this pedal used.

Are you sure that you have the cables going the correct way?
