My g-string broke 5 days ago (hehehe g-string), but seriously, I think there might be a problem because it broke again today. I have noticed that I'm breaking a string around every 3 or 4 days, and it's always by the saddles. I have filed down the saddles after every time I break a string so I'm pretty sure the strings aren't being cut by a sharp thing. I'll appreciate any advice.
