About three or four months ago, I ordered my first ukulele- a Lanikai LU-21. Considering I had never played the ukulele before or ever really even seen one in real life before, I didn't want to spend too much money and then find out that I didn't like playing the ukulele (little did I know how addictive it was!). Although the ukulele is not bad, I would like to improve it a little until I can get a new one. My ukulele is sounding a little dull and not staying in tune for very long. I was thinking about buying some new strings and tightening the tuners. What kind of strings should I buy? I was thinking maybe some bushman strings. Can you use them on non-bushman ukuleles? Or what are some other good strings? Are there any others ways as well to improve a ukulele?
