I own a classical Spanish guitar, more than hundred years old. The winders are made from wood, standing out through a board at the head. When I played last I used nylon strings which give a far better sound than steel strings. But the non plus ultra are catgut strings which gave the most wonderful sound, but they were breaking too fast. So I had to give up this usage when it became too expensive. Now I have the money but can't play any more due to a broken left wrist - alas!
