they're the strings that you get on a new Strandberg guitar from the manufacturer. which is great.
they bring a wonderful sense of "unity in tension" from string to string, are very stable at keeping in tune, and provide plenty of attack, and an even tone across all strings, all frets.
so why the stars missing, then?
because durability, in terms of tone, doesn't match my standard, and not even half of it (Elixir Nanoweb) – it's my first remark.
and, second, when playing clean and very quiet, mechanical noise of the left-hand fingering is quite high, actually a lot higher than my standard again (Elixir Nanoweb).
i'm aware that Strandberg guitars are specifically aimed to guitarists who love to drench their tone in distortion, so it's surely just myself to not fit the users' pattern with which this kit is sized and boxed specifically for Strandbergs... so this means you'll (most likely) fall in love with them, if you're that kind, instead.
to me, the bargain between even tension (on this specific 7 string multiscale guitar) against loss of durability and silence of left-hand fingering isn't exactly rewarding, so i'll most likely get back to Elixir Nanowebs, despite the technical prowess of these strings (made with clearly a different type of user in mind).
