On my acoustic, I found that it was really hard to play barre chords. I switched my strings to a lighter string and tension until I developed more strength in my wrist. I also made a few minor adjustments to my guitar... *cough* *cough*... such as filing down the saddle to lower the action.
Anyway... good luck! <img src="images/smiley_icons/icon_razz.gif" border=0 alt="Razz">
