Peg head angle adjustment and string longevity.

March 18, 2021, 1:40 PM · I have read how to adjust the angle of the pegs so they are at the optimal angle when tuned to pitch. That ideal angle is such that the upper edge is approximately 30 degrees from vertical toward the nut with the instrument horizontal. This position makes it much easier to tune while bowing. I am presently using Oliv GDE and Passione A, and the A has been stretching for a while. I don’t want to risk damaging the string by loosening it to adjust the peg angle.
I wonder if loosening the strings to adjust the pegs reduces the longevity of the strings. Is it the same for gut and synthetic?

It's just one of the reasons I switched to geared pegs (Knilling, Peghed and Wittner) a decade ago. They're so easy to turn that the angle doesn't matter.

March 19, 2021, 6:50 AM · While I do appreciate your suggestion, I prefer to continue using my friction fitted, 18th century technology pegs. I am still seeking any input that goes to my question. Does loosening the strings completely for peg adjustment or any other reason, cause damage to or reduce the playing life of strings, either gut or synthetic?

From my experiences so far, I will recommend that people do this as little as possible, if one prefers the sound and playing properties of a newly installed string, versus one which has been used for a while.

I do adjust pegs for a convenient tuning orientation, but I usually wait about a week before doing so with a new string, if possible, so the string will have stretched to somewhere near its final length, so the adjustment won't need to be done multiple times.

March 19, 2021, 2:31 PM · David, Thank you for sharing, I will probably do as you do, and wait to allow the string to settle in at its final length.

Here are 2 photos of the “ideal” positions:
