Here are a few ukulele string sets to try out first. These are sets that have a good reputation among ukulele players. I personally like the full line of Martin Ukulele strings and the Ko`olau 'Alohi strings.

• Martin Ukulele Strings - Martin Clear Fluorocarbon Ukulele Strings

  The Martin strings are the strings that I currently use on all my performance ukuleles.

• Ko`olau Guitar & Ukulele Company - Ko`olau 'Ukulele Strings
• Aquila - Nylgut 'Ukulele Strings
• Worth Strings by Worth Creations - A wide range of tensions

Now using the new Martin Clear Fluorocarbon strings exclusivity.

I bounced between the Ko`olau `Alohi Strings and Savarez Alliance on my performance tenor ukuleles for years.

I bounced between the Ko`olau `Alohi Strings and Savarez Alliance (Red Card-R) on my tenor ukuleles. Savarez now makes a dedicated ukulele string set for soprano/concert and tenor ukuleles. No low G, so I use the D'Addarrio Pro-Arte J4304 for the Low G. These are the same Alliance KF stings that I've always been using just in a ukulele package.
