Weird thing. I recently acquired a LP Special that came set-up with .010 - .046 strings. I played it and I liked it, even though I've played mainly on .009 - .042 sets for years now. I've never liked the extra stiffness of the slightly heavier gauge, and was always mindful of RSI problems. So, I was happy to play my extra lights all night without breaking a sweat.
But after playing the LP Special fairly intensively for a couple of weeks, I've found my .009 - .042 strings on my other guitars now feel like limp spaghetti. Blech. I don't know if playing the heavier gauge set on the LP has noticably strengthened my fingers in such a short time, or whether it's purely perception, but anyway, I've bought five new sets of .010 - .046 to start replacing strings on my other guitars.
I'm not sure how this is going to work out. I think the reason I like the .010 - .046s on the LP Special is because for whatever reason it seems to be a particularly slinky guitar... can't really figure out from the set-up why that might be. The stop tailpiece is screwed all the way down to the deck, which usually adds stiffness, for example. So something else is going on. But whatever it is, it probably won't be going on with my other guitars, so I'm not sure how well the heavier strings are going to play on my other guitars.
It's weird because I've played extra light strings forever (I remember reading back in the 70s that Jimmy Page used .008s at the time, and thinking that was good enough for me!) I've tried heavier strings from time to time but never felt a compelling reason or desire to switch. Quite the opposite. And now this... it's like the strings are choosing me, rather than me choosing the strings.
Anyway, I thought I'd share the anecdote to see if anyone else has experienced a similar situation. Soggy string blues: "Woke up this morning, and my guitar strings just didn't feel right/ Woke up this morning, and my guitar strings wouldn't put up no fight/ Had to go down the guitar store, and buy me five sets of D'Addario lights"
(Webstrings actually, but I'm a cheapass...)
