The original strings on a ukulele are likely to be low quality (unless your ukulele is an expensive model). I was advised to replace the strings with better quality ones and I must admit it did make a big difference to the overall tone of the instrument. The 'Aquila' brand of strings come highly recommended.
Don't do this right away if you are a beginner - wait until you gain confidence playing the instrument - it will improve the tone of the instrument but that can wait - the most important thing is to start learning how to play.
Before you attempt to remove the old strings and replace them with a new set watch the YouTube video below.
