It's a brand new Danelectro Longhorn bass model which has rounds fitted with the new style guitar tuners. I can't find out the gauge used on them, the length doesn't matter because they're cut. In fact there is very little info available on the new models at all.

(edit)
OK I compared them with some strings I have and they're very near 45-105. Only thing -the E isn't taperwound at the bridge but it is at the tuner, because it is a guitar tuner.
