Not to hijack the thread but I was looking forward to trying those cobalt strings!
I'm trying a different gauge of slinkies (9-46 in place of my standard 9-42) for the next change just to verify if I'm comfortable w/ it and then I'll try the cobalt.
The other thing I mentioned in that other thread is that for me how often I change strings also depends on the guitar. My Les Pauls being naturally much louder, the strings on them don't sound as muffled as they do on my strat.
2 sessions w/ the strat and it sounds lifeless. Not that they get harder to play or anything, they're still pretty smooth, but w/o that fresh strings sound, the strat sounds lifeless.
