2504C Sign. Ser. 7 Str LTHB : Great for downtuned 7 strings

I bought these specifically to play down tuned metal, and they do a great job of that. The 7th string .60 holds its tuning on my 25.5 scale guitar even when picking aggressively whilst tuned all the way down to A. String tension and bending was still comfortable on the first, second and third strings. In standard B 7 string tuning, the .60 was a bit too much for my fingers to play comfortably, but that's not why I bought them. The .60 string is very large obviously, I barely managed to feed it through the locking machine heads of my guitar. I haven't had any unusual problems with these strings breaking or corroding, Dean Markley are as good as any of the other top string manufacturers.
