Like many other people I have a bit of spare time at the moment and thought I would see one of my instruments sounded like with different strings. I was given a set of Stagg strings by a friend a while ago and decided to try them on my Baton Rouge long necked soprano as the ones it came with seemed a bit squeaky at times. It is a while since I had changed nylon strings on a guitar but I had little problem fitting the new strings but they seemed to take a long time to settle down. After a period of 10 days the new strings still would not stay in tune is this unusual ? I know I may have not pulled the knots on the tie bar bridge tight enough but surely they should have settled down in that time. I was glad I still had a couple of instruments around that stayed in tune as I was finding it very annoying.I have now restrung the Baton Rouge with its old strings which seem settle down ok as they had been stretched before. I wondered what I had done wrong was my knot tying wrong or are the strings just inferior? They did seem a bit heavier gauge than the originals which may have been Aquilla even though there was no label on the uke when it was bought. The sound was pretty dire anyway and the original sound fault may have been my bad fretting. I was wondering if strings take that long to settle down.
