I have LaBella vihuela strings on my 56cm string length instrument, tuned i A. But I have alsways felt that the strings on the 6th course were dull and lifeless. Well, I thought there was nothing to do about it, and that this was natural for such a small instrument. But today I replaced them with Pyramid strings meant for the 5th course of an 8-course lute, and this made a huge difference, the sound became crisp and full of life. Therefore I am interested in good advice regarding vihuela strings from other members of this forum.
