Bose Imperial Bass Strings

[David Love]

My understanding is that unwrapped portions contribute to inharmonicity,
more unwrapped, more inharmonicity.  Ideally, you want the wrapped portion
as long as possible without it touching the agraffe (or bridge).

strings were made from my measurements. He purposely tries to make the
wrapped length as long as he possibly can with the winding touching the
bridge pins or agraffes. I forget all his rationale, but I think the
advantage is to simply fully take advantage of all the length available to
make the string. As I recall, the winding came within about 1/8-inch of the
pins and agraffes (maybe it was further, but I do remember it being
amazingly close). Seem to me to make sense to get them as long as is
possible - but not risk touching. How much will a string stretch over the
years? I don't really know.
