I'm a long time user of the Elixir Nanoweb series.
All my guitars are equipped with such strings, varying the gauges depending on tuning and scale length.
This string set was made having in mind multi-scale 8-string guitars. Which is good!
Sound is tip-top, as ever, exactly as you'd expect on an Elixir Nanoweb string set. These are incredibly durable strings, be it tone-wise and resistance to corrosion.
However, there is one thing that has to be of attention on this particular set: the 8th string is a .074 gauge string. The gauge goes all the way from the ball-end until the very tip.
On my guitar (Harley Benton FanFret-8) I had to enlarge the tuner hole to acomodate the string. It is a 1min job, provided you have a Dremel and a metal bit.
Besides that, no other remarks!
As ever, I thoroughly recommend these!
