Hey all! I have that ES-335 that I bought used about 2 years back. The knobs cracked on it, the hardware is getting mate and there is that weird bubble under the finish (see pics). I know it is not normal but could it mean? Does it mean My basement is too humid? Too dry? It sucks for the knobs but I just want to make sure the whole guitar is not gonna crack bend or anything...
