A lot has to do with the way you've learned to play. The right hand technique for getting great tone and sustain out of a steel stringed instrument played with a pick won't work on nylon strings. Good technique for producing tone, volume and sustain on nylon strings is more difficult to learn.

To further complicate the picture, it's more difficult to make a great sounding nylon stringed instrument. The strings are under lower tension and have less energy to give the vibrating top.

Cindy Kallet plays on steel strings with technique based on nylon string playing and gets brilliant results.

And, for all of you nylon strings players who have the usual problems with string stretching, try carbon fiber strings made by Savarez. They sound great and settle in fast.
