Well, my mint Chroma Polaris was attacked by a falling ride cymbal
resulting in two bent and damaged sliders in the filter section on the
left hand panel: resonance and sweep depth. They are both loose and
nonfunctional. Resonance slider does respond if you press very hard
on it.

I have never cracked open the Polaris (no need as the membranes are in
excellent shape). Can the sliders be easily replaced (or swapped)?
If so, does anyone have two spares or can direct me to a source for
parts? Or, is an entire replacement left panel needed? (I hope not!).

Thanks in advance!
