The rule I use is Koa Ukuleles sound best with Aquila or D'addario Strings. Mahogany Ukes sound better with Worth. The exception to this is Koaloha. Spruce goes either way.
Laminates generally like Aquila Strings (except for Kiwaya) as well. I think Worths are so much better than Aquilas on Flukes and Fleas. Kiwaya laminates tend to like the fluorocarbon types, including Worth. The same rule applies for their solid ukes. 🙂
@hermanvdc had this to say on the subject of Ukulele Strings:
Indeed, Aquila helps give more brilliance to cheap ukuleles but on good the better ones Worth and especially Orcas sounds better!
So, I figured that I should post this so that everyone can make up their own mind and then give you some links to buy Orcas and Worth Ukulele Strings.
Two weeks ago I was running pretty much ragged with work and family visiting, etc. I pretty much didn't know which direction I was headed. But, sometime during the two weeks window of insanity, I had the clarity of mind to order some new Aquila Ukulele Strings and then pack them into my ukulele case (for my Lanikai CK-TEQ). Then I surprised myself even further by remembering to pack my Ukulele and my flipVideo when I had to leave town for a week-long job. Long story short? I had new strings and the means to make a before and after video in my lonely hotel room. Boo-yah!
Hopefully you can tell a difference from that video, but I think it's definitely more clear during the single note stuff. On the Aquila Strings it's just so much more percussive and it really rings out. I'm totally loving these strings!
I mention Musicguymic in this video. He's a big eBay seller and I would consider him a great resource for any ukulele-related purchase. Hell, he's got almost 600 ukulele-related items up for auction right now. I'll include a few sample items at the bottom of this post, or you can check out Musicguymic's eBay Store.
I was going to make a video showing everyone how to string their Ukulele, but I'm not a big fan of re-inventing the wheel and Aldrine from UkuleleUnderground.com already made this great video:
So, if you need to re-string your uke (and if it's been so long since you've done it that you can't remember, then it's time), I would highly recommend Aquila strings!
