I started a thread about normal or hard tension strings back in April, when I picked up a used Hohner HG-14 Japanese vintage classical. I haven't owned a classical in 31 years, and I was asking about pros and cons of hard tension strings. I had never used them before (I had a classical from 1973 to 1983), and wondered if I'd like the feel of them better than normal tension strings. I put a set of D'Addario EJ-46s on my guitar tonight. It's still too early to give my impressions, because the strings need to settle. I tuned them up, played them, and they went out of tune right away. Tuned and played them several more times. They're still going out of tune right away. It's been a while on all of this, so I'm not sure how long a settling in period to expect. I'm thinking at least several days. What do y'all think? Longer, like a week? Also, I'm getting some string buzz. Will that go away once they've settled?
