Hi, re big fingers, i've also got big hands/fingers, I struggled for years with various guitars until i found out that a few guitars are made with a wider nut, typically 1 3/4", 1.8" or 44/45mm instead of the 1 11/16" normal nut (I think), and they often call them fingerstyle guitars (epiphone masterbilts, takamine, martin, the top of the line yamahas etc all do wider necks). I sold on my washburn and yamaha acoustics and searched for a seagull acoustic (solid woods made in canada), got a nice 2nd hand one (they are all around the 1.8" and known for a wider nut). I got it set up nice by an actual luthier (someone who actually makes acoustic guitars for a living) and haven't looked back. For an electric strat you can get wider necks from warmoth online, they even make a jumbo wide neck for a strat. I hope that helps, I know there are a lot of folks who say it makes no difference etc, I don't care if it's all in the mind, I'm a lot happier and enjoy playing my wider neck guitar. All the best, Mike :)
