As you may know: there are a lot of american made strings out there, so when i first saw these Rotosounds I just thought: wow, some british made strings, i will have to try them!
So I put a set of them on my guitar and was positivly impressed. The sound is very warm and round, more bass and mids, less treble. Thats why it works really well with my SG.
One thing i dont like, is that these two sets of strings are just put in the package all together, so if you want to change a single string, it could get a bit difficult.
