5 1/3 rank

I have never gotten the 5 1/3' rank to sound good. After reading Walter Strony's book again, I now realize it is a harmonic of the 16' sound so you need strong 16's. I was always just using it with a 16' Tibia and it wasn't working. You need to use 16' color reeds and strings to give a good solid 16' base. I now hear how it should sound.
