Re: both pots are stuck
That sucks. ..
I've had to do surgery on a few guitars that had glued on knobs..
My first thought would be a corrosion issue, but you would need a lot of humidity for that to occur. .and it wouldn't be just the pots that would show corrosion if that was the issue...
I wouldn't call sticking the pots wide open a mod, personally, kind of defeats the purpose of a pot,unless you were controlling volume with a pedal and wanted the tone wide open, but stranger things have happened! !
If you can't get those knobs off you'll have to break the pot down from inside the control cavity, not fun , but it's fairly easy.
