I buy whatever the store has, so I've gone through quite a lot of brands over the years. Gibson, Martin, Rotosound, D'Addario, Elixir, Ernie Ball. I prefer Ernies of the bunch, they just feel smoother. And for my Spanish I've used Ernies, Salvarez and Hannabach. Hanna's is pure <3
This looks like a good thread to mention once again what a cr@ppy country I live in. I've never, in my life, seen a guitar string thicker than 0.056. The stores simply don't have them. Attempts to get strings for my 7 at a gauge I actually like have proved futile. I neeeeeeeeeed a set of 010-065. :(
