I have nothing but good things to say about Elixir strings.
Purchased this for a 26.5" scale 8 string I have. It use to have an Ernie Ball .074 on, so this definitely improved the situation. Elixir strings to me are just magic, they last way longer, they feel way smoother and sound way crispier than any other brand. I just don't buy anything else anymore because when I did, I always ended up taking the strings off any guitar after just a couple days, I just can't stand any other brand anymore.
However specifically for an 8 string guitar, and this has got nothing to do with the string itself, it's just my opinion on a side subject, I feel a slightly thicker gauge would have been a better choice, maybe 90. Unfortunately for guitars Elixir only goes as high as 80, so I am probably gonna get a .090 bass string.
