Guys: I have one of those stand up guitar stands that has a place for two guitars to sit, back to back. The kind that has a cradle at the bottom, and a neck holder at the top? Unfortunately, one of my guitars is almost twice as heavy as the other and it has made the stand easy to push over. I've not had a disaster yet, but I've come close. I really need a better option. Anyone point me to something? like that?
