I don't have an Eminence, but I do have a BSX Allegro, so a similar kind of EUB.
I put a set of Silver Slaps on it when I bought it in November 2010. The same strings are still on it now, and I have had no problems whatsoever keeping it in tune. In fact, the strings are so stable I hardly ever have to tune it!
Cheers
