I have lefty fender stratocaster that I switched around about 6 years ago to fit my right handed playing.

My question is about the whammy bar. I just started playing again after about a month break and the whammy bar feels sticky. I don't really know how to describe it. I can't smooth into it, it jerks and feels really stiff after it jerks. It also sounds like the bridge may be rubbing somewhere.

I'm wondering it cold weather could do this and/or if this is a common problem that needs fixing?

Any help is appreciated, thanks.
i have no idea what your talking about.

Maybe spray the springs with WD40 or something, they stiffen up after not using them for a while
