I use this with my 27" 8 string guitar tuned EBEADgbe. I previously used bass strings for the lowest string, but it just didn't have the right timbre or feel. This string is works much better, nice balanced sound that works great with whatever 7 string set I pair it with.
A quick tip to large strings- due to the thickness of the string, it will probably bend at a sloped angle on the bridge, which can make it sound dull. Just push the string down hard in front of the bridge to get a more sharp angle, and the string will sound much better!
Good things:
-Price
-Balanced sound
Bad things:
-Nothing really
Would definitely recommend this string if you want to tune real low.
