When I bought my ukulele it was tuned with a high G. Can i just tune it down or do I need to get a new string for the lower G? Or can I just leave as is?
The high G string won't tune low without going all “wobbly and weak toned”. You'll need to purchase either a new string, or I would recommend buying a new set of Aquila strings with a Low G. They make a number of string types. I prefer the “nylgut” strings because they carry a bit more tension and they have a really nice tone to them. You will need to buy the correct set for your uke size.
