My RP23 has developed a really really annoying squeak when pro pedal is on (happens in all pro pedal modes). As soon as I turn pro pedal off, the squeak is gone, see video:

Will this require a complete rebuild to fix? I read somewhere it has to do with the harmonics of the dampening feature in the shock but it isn't harmful, just annoying. Can someone confirm that?

Thinking of sending it to Push to get it tuned at the same time but if there's a much cheaper fix to just get rid of the squeak, I'd rather do that for now.
