I put a set of .10 Cobalt Slinky strings on my American Special today and don't know if I love them or hate them. I know this sounds odd, but there are pros and cons to these strings and I can't figure out where I stand on them yet. I really wasn't expecting there to be much difference between these and the 10.5 D'addarios or Power Slinky I usually use, but there is. They give the guitar a sort of baritone guitar type of feel and, to a lesser extent, tone. Here's where I'm at: Pros They feel bigger than .10 gauge strings and have more "fight" than the Daddario 10.5 strings I had on before. They impart a deeper, "ballsier" tone on the bass strings and the trebles seem more powerful. They didn't take long to stabilize and seem to stay in tune exceptionally well. Cons They're harder to bend than the Daddario 10.5 strings I had on this Tele! The wound strings are noticeably more coarse feeling The bass strings have a deeper, meatier, "piano like" tone, but with a metallic "grit" They required resetting the intonation and lowering the neck pickup because the low E string was producing a muted thud on the high frets from being too close to the pickup. I'm leaving them on, but have mixed feelings at this point. If you've tried them, what do you think?
