Seasonal setup and trem claw tightening
I noticed that now that summer came, I needed to slightly screw the screws of the trem claw, in order to achieve the same parallel position of the trem plate as before.
I had many incidents like this, back from Oct->Dec when I finally stabilized the guitar. I hadn't touched any tool since then, neither did I change strings. However lately I noticed several open notes going flat according to the digital tuner, so i re-tuned the guitar only to find out that the trem plate angle was not how it used to be and is supposed to be, but had an angle towards to the bridge. So slightly I tightened the two claw screws. Now all readings, measurements are like before.
My question is : is possible that weather affects the springs/claw/screws ?
