This belongs to a friend of a friend, who's the lead singer for a band called NEVERFRIEND (sadly misspelled in the video at the end). She complained it wouldn't stay in tune. A few simple tweaks and a properly strung up guitar, should solve most of the problem. Stretching the strings before every performance will also help:-) (That's Paul Gilbert's advice BTW)
