I too am having this difficulty. I am learning on an acoustic. I have enormous fingers and physically cannot fit them into the space. I know there is a way to overcome this ... some of the greats had big fingers. I have tried to use two fingers, but can't consistently get all the strings to ring properly. I have some success just barring across with my index finger, but cannot get consistently good sound. I think if I were playing an electric, I might not have as much difficulty because it wouldn't take as much strength in my fingers to barr??? Any other suggestions???
