When buying an 8-string I needed some replacement strings, and these were some of the ones I wanted to try. I only use Elixir normally, but seeing that they are either very limited or expensive when it comes to different gauges, I went for these since I used D'addario before Elixir and this set seems to be pretty "go-to" in the ERG community. The guitar I fitted them on was an Ibanez RG8 with a 27" inch scale. First impressions were good, but went south after a bit of tinkering. First of all, light strings were too tight, and a 27" scale isn't even that much for an 8 string. The 74 for the low f# seemed too light however, at least for the scale length. The tension jump to the 64 for the low b is just too steep, and the string was very tight. The sound however was very good. Nice for tight heavy rythm, just not on the f#. Overall, okay considering the options out there but still a very unbalanced set.
