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.
I've used most strings over the years, and I always seem to return to D'addario. And with good reason, they are really really good strings! EB's tend to sound dull and flat to me pretty quickly, whilst D'addarios have always felt more musical and sounded tighter. (Yes, they will Djent pretty well too!) I have used this string on a 30" scale String through guitar with a reverse head stock, and it's still long enough for that. So 99/100 they will fit perfectly and have no problems. They taper later than other brands as well, which is good as I have found that some strings taper over the 1st fret of my guitar, meaning that they buzz really badly. D'addario's customer support is great as always and they care as much about the first time buyer as they do their endorser's. My only point for improvement would be for them to offer even thicker gauges in future so I can run them on a 9 string without having to resort to bass strings. Maybe even up to .120?
