Hi, I'm helping a friend setting up a Rick 450/12. The tail piece is the kind where there are only 6 holes and you double the 12 string pairs in one hole. Unfortunately, I didn't look closely before taking the old strings off. Is there a trick to restringing those? I'm guessing put the thicker string in in the bass side first. then tuck the octave string behind it. I did try searching to no avail. Thanks!
