Hi, OK, I think this may go along the lines of the nylon vs steel strings thread, but I wanted to ask anyway. So this may sound funny, but I was watching Parenthood last night and one of the dudes is a rock star and he bought his daughter a guitar with "light gauge guitar strings 'the 10's'" so she could "play all night" and it wouldn't hurt her fingers. Are light gauge guitar strings all nylon then? Just curious. I've got the steel ones and my fingers, although developing callouses, if I skip a day or two of not practicing I feel like they go away...maybe just not fully developed callouses yet? Anyway, when I heard this it intrigued me.
