has anyone ever tried this?

[Willem Blees]

The problem with any kind of jig that would pre-stretch a string?is that bass strings come in a variety of lengths. A string for the single strings would be need a much longer distance from hitch pin to tuning pin than the string up in the tenor section. The jig would have to come with a moveable hitch pin. The other problem is when you turn it on the tuning pin, for an upright it might not be a problem, but for a grand, you're going to have a heck of a time putting that string through the agraff. 

Hanging a weight on the end of string might be the best solution, but in order for it to be effective, you would need a weight of approximately 150 - 200 pounds. How are you going to attach that much weight to the end of a string?

Sorry, Brian, but there is not easy solution. Sometimes we just have to do what we have to do, and leave it that.?

Brian, 
While I don't know if Mike Spaulding is 100% correct that "it's all in the bends", but if you really wanted to pre-stretch the string your could take some old pinblock(s), pound in a hitchpin, perhaps make some kind of bridge, drive a tuning pin in an appropriate tuning pin hole, and pull it up to tension. So .. if you really want to pre-stretch, make yourself a monochord.

Sorry for the confusion.

I still can't believe that someone has not discovered a way to "pre-stretch"
a new bass string.??Maybe something like hanging a weight on the end without
the loop?
