I bought a KoAloha soprano the other day and have been trouble with finding the right strings. I got some suggestions from you all (thank you) and have some sets on the way to try. I have noticed that the tuners were EXTREMELY tight! I loosened them and would adjust them but then they did not seem to hold. I tried a vriety of tensions but they just seem faulty to me. I really like this uke and think I should upgrade tuners from the stock K tuners. What is an easy swap with these and work good? Any ideas? Thanks.
