Hi, I bought a Godin A5 a while back and after playing it for a while broke an E string. I've broken strings in the past because I've got a strong right hand plucking technique, but not for years, and I'm pretty sure, never an E, just a D or G here and there. I put on new D'Addario flats on it maybe 3 weeks back and have had to retune pretty much every time I picked it up, but didn't think this unusual. The B string I've noticed for the last week or so has really been out. When I was tuning it today, it broke at the tuning peg end. I would tune it to pitch, play the harmonic, it would be low (like it slipped), tune it up, check, it would be low, and so on until it broke. I wasn't over tightening, just gradually tuning it up to the corresponding harmonic on the E. Any idea what might've caused this to happen? Thanks.
