Black parchment for wound gut A?
I recently got a tricolore A with aluminum winding and upon tuning it, the winding failed almost immediately (at the nut and then at the bridge). Upon inspecting the packaging, I realized a small piece of black parchment was included. I'm now assuming this was supposed to be put under the string where it meets the nut and bridge, to act as a lubricating surface for the relatively fragile winding?
Darn, bad news. No, and I am sorry. My recent Pirastro Oliv A (week old) came with a rubber protector for the bridge, but I did not use it (much like with E protectors I also never use.) In another thread I mebtioned that Oliv A's winding going slightly loose, but not at the nut or bridge for sure.
I think it came with the black parchment for that reason. The D and G didn't come with it, but their windings have given no trouble at all.
Yes it is for the bridge. Do you already pencil the nut and bridge everytime before putting on and new string?
Graphite is very important. Need to pencil the slots.
I do believe Mr. Williams knows of the common tips above. The likely culprit may be the string.
Could be a bad string, Could also be a problem with grooves.
That will sometimes happen with DIY nuts and bridges.
Maybe I'll just throw the previous plain gut A back on for now. It's possible it's the grooves in the nut. Although they're professionally done, it may be that they need to be catered to the extreme fragility of the winding on the gut string. Still, I'm going to reorder the string just to see if using the thin parchment provided makes a difference.
One more detail: to help a string stretch initially, secure the fiddle on your lap, (hold the neck with your left hand) place the thumb on the top of the bridge and pull the string 1-2mm up with index and middle finger. Tune it, then repeat after a few minutes of playing.
