if your fingers are too big for your fretboard you can always try one of those wider ones,be careful though with that route, i tried a wider neck guitar when i was having the same problem right at the beginning but my hands weren't big enough to get around it properly (try before you buy) usually its all just about perseverance and practice, trying not to do a Pete Townsend in the meantime
