Hi, over the last few years I've delved into doing my own setups on my Fender JB after reading extensively on all aspects.
While I'm aware of the typical need for seasonal truss rod adjustment, I'm not clear on whether simple room temperature can be a factor on a day-to-day basis.
I only play in my loungeroom, which during winter, varies in temperature by 10 to 15° celsius (50 to 75° fahrenheit). Could this cause truss rod issues?
