There has been a lot of cabs built of various sizes but there does not seem to be any naming convention for them. Anything smaller than full size is just referred to as Mini which has been used to described 3/4 scale cabs down to 1/8 scale cabs like Benders Donkey Kong.
I propose we have some naming standards (if its possible - if not this post will highlight it). Below are my first cut at some naming standards for uprights, please feel free to add your comments and ideas on cab size's and there names.
Full Size: A cab built to original cab specs or a cab built to over 51" Tall
Mini: 12" - 51" Tall
Micro: 5" - 12" Tall
Nano: Anything up to 5" inches tall
