Hello all im new to this forum and the ukulele,I just bought a mahalo tenor uke today and have been having fun playing it.The problem im having is with tuning stability.When i tuned it to pitch the tuners kept slipping so i replaced them with some old guitar tuners that were laying around.Now they still slip but not as drastically as before.Could the problem be with the strings?The factory strings are the clear ones.Being new to the uke im not sure about the strings or whether they need time to stretch like guitar strings.Any suggestions?
