If the action is high as in hard to play light strings can make all the difference in the world a friend of mine gave me a guitar and it had like medium gauge strings on it and it was hard to play I threw some ultra light strings on it and it played like butter he was all oh man I want that guitar back. So if you see extra light or ultra lite maybe try em out if they are too light and you get buzzing on the frets try just a light gauge.I haven't tried changing the strings to lighter no - what difference do smaller strings make? (Real question)
