I tried the cobalt strings in 9's on a JS1000. It brightened the sound of the instrument up, which I did not like.how do you think it would sound with a basswood body and infinity pups? its already a very bright guitar, how do you think it would panm out?
I had also read that the cobalt would wear your frets out quicker than regular strings, but that may not be true. Anyway, I removed them and went back to D'addario.
They (cobalt) did feel good, and they sounded good, but I just didn't like the way it changed the JS sound. I think if you would want to brighten the sound of a mahogany body guitar, they would be the ticket.
