I have large fingers as well. I have been playing for about 7 months and have recently went to extra light strings. This has helped tremendously although i have lost some of the "boom" of the accoustic. Dont be afarid to try different fingering techniques as well. My F chord and A chord are just a little different than normal. I was getting frustrated but needed to carry on with these chords so i adapted. With the help of the people on this site and perserverance, it will all work out
