Re: js1000 or js1200 strings
I've used Ernie Ball and Dean Markley over the years, but I've found the D Addario ones last longer against corrossion and stay nice and bright with their tone. I always wipe my guitar down after I play and I've found that to help. Never broke one of the D Addario and I've left them on some of the guitars I don't play as often for a long time and they still sound good. I also think those are the type that Rich uses as his standard. If you haven't played in a while, 9-42's will be easier on your fingers than heavier gauges.
