My string is unraveling on the bridge!

September 27, 2022, 12:27 AM · Hi! My violin currently has Alphayue strings. I study and play daily. I travel almost every day to different places with different temperatures and humidity. I've had these strings for 3 months. What happens is that, specifically, the A string is wearing out, unwinding right at its bridge end. Exactly on top. The penultimate string change (with Pirastro Gold) took place in exactly the same place. Is it my bridge? Climate changes? Strings quality? What made me curious is that it was in the same place and on the same string and with a set of from different brands. I emphasize that my bridge is properly adjusted.

September 27, 2022, 6:17 AM · The graphite suggestion is a good one. Some other thoughts: could it be pressure/friction from the case? Where did you get your strings? It might be worth it to try another brand and see if things change.

I did have the same problem many years ago.

Also be sure the pencil point you use to lubricate your string grooves at the bridge and nut is pointed enough to get into all the string grooves and the lead is soft enough to do the job.

Also, check that the groove itself is properly rounded, that the string doesn’t sit too deep (1/3-1/2 the diameter of the string is ideal), and that there aren’t sharp edges to pinch the sides of the string. The same applies to the nut.

(pegs, I suspect, otoh, make the strings wear out quicker at the nut)
If you save your old nylon E-string sleeves, you could try one on the A string too.

Groove too narrow.
Groove too deep.
Use pencil graphite.
A Luthier can fix that. They have a set of special, very narrow files.

September 27, 2022, 3:57 PM · The above replies are very good for bridge grooves and graphite. I personally believe with lots of weather extremes and a lot of playing,
3 months is a long time for string life. It might be time to consider upgrading to Tonicas or Dominants for better durability.
September 27, 2022, 5:51 PM · I’ll add that aluminum-wound strings are more susceptible to unraveling, which is why the A string tends to be the one that goes bad first. Aluminum D strings have this issue as well.
September 27, 2022, 9:14 PM · Has anyone mentioned graphite yet?
