What happens if we lengthen the scale to say 25 inches and above? vs say 24 inch.
For a particular string and raise, say, is the lengthening of the string more on a 25 inch vs a 24 inch? Is the pull required, more on a 25 inch or less? I've heard it's easier to break strings on longer scale lengths. |

Hey Stephen, greets from, uh, Berkeley. There are a number of resources on the web, you might find this useful: http://www.mcdonaldstrings.com/stringxxiii.html. There is a tool that will calculate tension of different string gauge/scale length combinations. For PSG, you'll probably want to base the calculation on the highest raise pitch of a given string.
The bottom line is, the longer the string, the greater the tension for a given pitch. Same applies to heavier strings, the larger the string gauge, the greater the tension for a given scale length. The problem is obviously greatest on the lighter strings. A longer scale guitar should tend to break the lighter strings more, but YMMV. Most PSGs are ~24" - 24 1/4". I had a Sierra for a while with a 25" scale and never broke a string on it using standard E9 gauges (.011 G#).
b0b has a page here with some useful info too: http://b0b.com/wp/?page_id=259.
Hope this helps. |

Here's another simpler page. Don't know if it's better, but it's already in inches. I used it when I was designing my Uni 12 and it took the trial and error out of choosing the return springs.

Odd thing is, it caters for .019p which I didn't think existed but not for .021p which surely does. Maybe it's a D'Addario thing.

| That is a better tool, Ian. Pretty slick. |
