Had a clamp which was uneven so it closed down like a "V" with one end much tighter than the other. I didn't realize this until I pulled tension and the string slipped. Unfortunately, the string was also pinched, about 2 inches of it, so it isn't nice and round but flat as a pancake. I immediately stopped the job and fixed the clamp. Question: Can I still restring with the flattened string? How will the performance and durability be affected?
