Does anyone here play the Sonor Perfect balance pedal? I have a gig today and I'm having some trouble with it and can't seem to find any explanations.

At my last gig, I noticed this rod was coming out which made the hoop clamp come loose. I also found this spring next to it on the ground, not sure if it has anything to do with it.

If anyone has any ideas whether you own the pedal or not, please let me know. I don't want to go back to using my DW 2000 for this gig, haha.

I wish I could post a picture, but I am having trouble with that at the moment
