Anyone know what kind of strings are on an Epiphone Thunderbird by stock? I haven't changed them since I got them (just over 2 years now) and they are now better than ever, nice and thumpy. I think the gauges are 45-105, but I'm not sure. They sound kinda dull, but in a good way. Bassy, smooth treble. I haven't used any flatwound strings yet, but they do sound close to what I think flatwound strings sound like (no experience, though). So are the stock strings from a particular brand, or are they made by epiphone/gibson? One thing I'm sure of is they are neither GHS, Daddario or Fender, since the rings on the end are brass.
