hi: im going to freeze my sg standard tomorrow to get some real chekings. i hope it will be horizontal chekings, but i will be happy wherever it happens. i got some checking already this winter, but 1 month ago i bought a can of dust air, and sprayed the guitar so the chekings went bigger and longer. im going to freeze it so i can test how this method works. ill post whatever happens. but im going to put the guitar directly, no wraps or loosing strings, im just going to put it on the freezer. now on my house its 30 degrees so i think the change will be enough. im planning on let the guitar only 30 mins at -15 degrees.
