This just recently hit me. My school is purchasing a bass that I can use there so I dont have to bring mine back and forth. My bass is a full 4/4, and the one that the school is purchasing is a 3/4. I was just wondering, does the size also affect the scale length of the strings? Or will I have no problem playing both and switching back and forth? I'm a guy who knows what he's doing when it comes to electric basses, but I'm new to double basses. If I'm not mistaken, the regular scale length of the strings is 42"? Will this change from a 4/4 to a 3/4?
