As a general rule, I put long scale strings on long scale basses; short scale strings on "normal" short scale basses; and medium scale strings on... basses that force me into using them. But, IME, it's the particular bass itself, that decides which strings will fit. Examples;
- My '94 Gretsch Broadkaster is 30.5" scale. With it's trapeze tailpiece and floating TOM bridge, it should wear medium scale strings. Like the great majority of basses like that do. But, it's so big
physically, that a lot of medium scale strings won't fit it - they're too short. As in, they don't even make it to the tuner posts, too short. Conversely, a lot of long scale rounds and flats will fit it perfectly... Currently, it's wearing a set of stupid-long-even-for-medium scale, "short scale" TI Jazz Rounds. On the Gretsch's 2+2 headstock, the E and G strings barely needed to be trimmed to get 3 winds on their tuner posts; the A and D strings barely have 2 winds on the tuner post - without cutting them at all...
- My Chinese Starfire violin bass is another one with a trapeze tailpiece and a floating bridge. So, it needs medium scale strings, right?
Wrong. Although it doesn't look like it, this bass is actually 29" scale, and the tailpiece is slightly longer than is "normal". The "real" short scale Labella 760FL's it wears, fit it just fine... A perfect example of what happens when you ASSUME something. It often makes an ASS out of U and ME...
I've found that, with so much variance between the actual overall dimensions of bass guitars - combined with the equally wide variance in the length of strings of a nominal scale length, that it's never a good idea to simply assume that "x scale" strings will fit "x scale bass" without a problem. I've been wrong, more times than I care to think about... Measuring your bass, and looking up the actual length of the strings you'd like to use, is the best way keep from wasting your money on strings that... SURPRISE!! don't fit your bass. And, save
you the grief of having to learn this stuff the hard way - like I - and lots of others - had to...
