Maybe it's a common question, but I have no clue. I recently restrung my upright for the first time. In short, after changing my strings, they sound too "new" for me. I prefer a "round"/mellow tone. I'm one of those baddies that doesn't even like to change strings on fretless once a year (I typically play with fairly boosted mids and a little more bridge pickup + roundwounds anyway so I get all the brightness I want/need), but electric strings are not quite the same as the mighty upright's. The other concern is the simple feeling of them. I know that new flats always feel stiff, but they just feel unnatural to me at the moment. I'm guessing around six weeks or so assuming an hour of play a day? What do you think/feel from your past experiences TB? I'm looking forward to when I can consider them broken in, but it's just.. awkward for now!
