yes for me. We have a bit of humidity towards the end of summer and the neck changes (and requires adjustment) then and when we get into our winter - another change. I keep my guitar in the case and use a hygrometer and make sure they stay within the manufacturers recommended range. A good local guitar tech have been very helpful to me. Along with adjusting necks and doing setups, he provides good informal education on acoustic guitars. Well worth what I pay.
