Bought these to use on my Wolfgang, based on the gauge already on there. I've used D'addario strings before and really like them, although these days I tend to use either Ernie Ball or Rotosound 10's. I'd forgotten that they have a nice clear sound and feel,(I know most new strings have that, but these keep that feeling and sound for longer). Have to say, looking at the product page for the EvH strings, they actually appear to be in the same packaging as these, apart from the logo.....are "his" strings made by this company? If so, not to take any money away from Eddie, I'll go for these every time at a good £2 - £3 cheaper.
