Rookie question: what differences are there between different gauge strings? It's well known that Stevie liked to play thick strings when Fenders usually come with 9s. It seems to me that lighter strings would get less output from the pickups but be easier to fret and bend? Do thicker strings vibrate with stronger lower harmonics?? And thinner strings with exaggerated higher harmonics? One of my favorite guitars (Gibson) came new with a hybrid set from the factory and I'm wondering why they would do that, what advantages could there be? 9-11-16-26-36-46, isn't it strange that the steps between sizes are so uneven? I've read that many of you install 11s on your Gretsches, why??
